Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 115628, here are decompositions:

  • 31 + 115597 = 115628
  • 67 + 115561 = 115628
  • 157 + 115471 = 115628
  • 199 + 115429 = 115628
  • 229 + 115399 = 115628
  • 307 + 115321 = 115628
  • 349 + 115279 = 115628
  • 379 + 115249 = 115628

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 115,628 and was likely granted around 1871.

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

Position in π

The digit sequence 115628 first appears in π at position 915,342 of the decimal expansion (the 915,342ordinal-suffix:nd 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.
