Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 180876, here are decompositions:

  • 5 + 180871 = 180876
  • 29 + 180847 = 180876
  • 79 + 180797 = 180876
  • 83 + 180793 = 180876
  • 97 + 180779 = 180876
  • 103 + 180773 = 180876
  • 127 + 180749 = 180876
  • 197 + 180679 = 180876

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 180,876 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 180876 first appears in π at position 218,104 of the decimal expansion (the 218,104ordinal-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.
