Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8725406, here are decompositions:

  • 7 + 8725399 = 8725406
  • 43 + 8725363 = 8725406
  • 127 + 8725279 = 8725406
  • 163 + 8725243 = 8725406
  • 199 + 8725207 = 8725406
  • 223 + 8725183 = 8725406
  • 229 + 8725177 = 8725406
  • 307 + 8725099 = 8725406

Showing the first eight; more decompositions exist.

Possible US patent number

This number falls in the range of US utility patent numbers. If it's a patent, it would be issued as US 8,725,406 and was likely granted around 2014.

Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.

Position in π

The digit sequence 8725406 first appears in π at position 15,523 of the decimal expansion (the 15,523ordinal-suffix:rd digit after the integer 3).

Search range: the first 1,000,000 fractional digits of π. Any 6-digit-or-shorter string is virtually guaranteed to appear in there — the more interesting signal is the position.
