Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 180298, here are decompositions:

  • 11 + 180287 = 180298
  • 17 + 180281 = 180298
  • 59 + 180239 = 180298
  • 137 + 180161 = 180298
  • 227 + 180071 = 180298
  • 317 + 179981 = 180298
  • 347 + 179951 = 180298
  • 359 + 179939 = 180298

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 180,298 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 180298 first appears in π at position 364,323 of the decimal expansion (the 364,323ordinal-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.
