Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 157862, here are decompositions:

  • 31 + 157831 = 157862
  • 193 + 157669 = 157862
  • 223 + 157639 = 157862
  • 283 + 157579 = 157862
  • 349 + 157513 = 157862
  • 373 + 157489 = 157862
  • 379 + 157483 = 157862
  • 433 + 157429 = 157862

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 157,862 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 157862 first appears in π at position 668,172 of the decimal expansion (the 668,172ordinal-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.
