Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 182458, here are decompositions:

  • 5 + 182453 = 182458
  • 41 + 182417 = 182458
  • 71 + 182387 = 182458
  • 149 + 182309 = 182458
  • 179 + 182279 = 182458
  • 197 + 182261 = 182458
  • 257 + 182201 = 182458
  • 281 + 182177 = 182458

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 182,458 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 182458 first appears in π at position 981,453 of the decimal expansion (the 981,453ordinal-suffix:rd 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.
