Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 182398, here are decompositions:

  • 11 + 182387 = 182398
  • 59 + 182339 = 182398
  • 89 + 182309 = 182398
  • 101 + 182297 = 182398
  • 137 + 182261 = 182398
  • 197 + 182201 = 182398
  • 239 + 182159 = 182398
  • 257 + 182141 = 182398

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 182,398 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 182398 first appears in π at position 789,350 of the decimal expansion (the 789,350ordinal-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.
