Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 182890, here are decompositions:

  • 3 + 182887 = 182890
  • 23 + 182867 = 182890
  • 101 + 182789 = 182890
  • 179 + 182711 = 182890
  • 233 + 182657 = 182890
  • 251 + 182639 = 182890
  • 263 + 182627 = 182890
  • 311 + 182579 = 182890

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 182,890 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 182890 first appears in π at position 376,920 of the decimal expansion (the 376,920ordinal-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.
