Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 518470, here are decompositions:

  • 3 + 518467 = 518470
  • 23 + 518447 = 518470
  • 41 + 518429 = 518470
  • 53 + 518417 = 518470
  • 59 + 518411 = 518470
  • 83 + 518387 = 518470
  • 179 + 518291 = 518470
  • 233 + 518237 = 518470

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 518,470 and was likely granted around 1894.

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

Position in π

The digit sequence 518470 first appears in π at position 857,157 of the decimal expansion (the 857,157ordinal-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.
