Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 182406, here are decompositions:

  • 17 + 182389 = 182406
  • 19 + 182387 = 182406
  • 53 + 182353 = 182406
  • 67 + 182339 = 182406
  • 73 + 182333 = 182406
  • 97 + 182309 = 182406
  • 109 + 182297 = 182406
  • 127 + 182279 = 182406

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 182,406 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 182406 first appears in π at position 819,795 of the decimal expansion (the 819,795ordinal-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.
