Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 182380, here are decompositions:

  • 41 + 182339 = 182380
  • 47 + 182333 = 182380
  • 71 + 182309 = 182380
  • 83 + 182297 = 182380
  • 101 + 182279 = 182380
  • 137 + 182243 = 182380
  • 179 + 182201 = 182380
  • 239 + 182141 = 182380

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 182,380 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 182380 first appears in π at position 24,415 of the decimal expansion (the 24,415ordinal-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.
