Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 180624, here are decompositions:

  • 7 + 180617 = 180624
  • 61 + 180563 = 180624
  • 83 + 180541 = 180624
  • 113 + 180511 = 180624
  • 127 + 180497 = 180624
  • 151 + 180473 = 180624
  • 211 + 180413 = 180624
  • 233 + 180391 = 180624

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 180,624 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 180624 first appears in π at position 5,488 of the decimal expansion (the 5,488ordinal-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.
