Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 149372, here are decompositions:

  • 31 + 149341 = 149372
  • 103 + 149269 = 149372
  • 199 + 149173 = 149372
  • 211 + 149161 = 149372
  • 229 + 149143 = 149372
  • 271 + 149101 = 149372
  • 313 + 149059 = 149372
  • 439 + 148933 = 149372

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 149,372 and was likely granted around 1873.

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

Position in π

The digit sequence 149372 first appears in π at position 455,771 of the decimal expansion (the 455,771ordinal-suffix:st 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.
