Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 180844, here are decompositions:

  • 47 + 180797 = 180844
  • 71 + 180773 = 180844
  • 113 + 180731 = 180844
  • 197 + 180647 = 180844
  • 227 + 180617 = 180844
  • 281 + 180563 = 180844
  • 311 + 180533 = 180844
  • 347 + 180497 = 180844

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 180,844 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 180844 first appears in π at position 464,212 of the decimal expansion (the 464,212ordinal-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.
