Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 180892, here are decompositions:

  • 113 + 180779 = 180892
  • 191 + 180701 = 180892
  • 263 + 180629 = 180892
  • 269 + 180623 = 180892
  • 353 + 180539 = 180892
  • 359 + 180533 = 180892
  • 389 + 180503 = 180892
  • 401 + 180491 = 180892

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 180,892 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 180892 first appears in π at position 272,877 of the decimal expansion (the 272,877ordinal-suffix:th 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.
