Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 182290, here are decompositions:

  • 11 + 182279 = 182290
  • 29 + 182261 = 182290
  • 47 + 182243 = 182290
  • 89 + 182201 = 182290
  • 113 + 182177 = 182290
  • 131 + 182159 = 182290
  • 149 + 182141 = 182290
  • 167 + 182123 = 182290

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 182,290 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 182290 first appears in π at position 553,019 of the decimal expansion (the 553,019ordinal-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.
