Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 493390, here are decompositions:

  • 89 + 493301 = 493390
  • 113 + 493277 = 493390
  • 173 + 493217 = 493390
  • 179 + 493211 = 493390
  • 197 + 493193 = 493390
  • 251 + 493139 = 493390
  • 257 + 493133 = 493390
  • 263 + 493127 = 493390

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 493,390 and was likely granted around 1893.

Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.

Position in π

The digit sequence 493390 first appears in π at position 376,529 of the decimal expansion (the 376,529ordinal-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.
