Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 187534, here are decompositions:

  • 3 + 187531 = 187534
  • 71 + 187463 = 187534
  • 101 + 187433 = 187534
  • 167 + 187367 = 187534
  • 173 + 187361 = 187534
  • 197 + 187337 = 187534
  • 257 + 187277 = 187534
  • 311 + 187223 = 187534

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 187,534 and was likely granted around 1875.

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

Position in π

The digit sequence 187534 first appears in π at position 702,801 of the decimal expansion (the 702,801ordinal-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.
