Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 938470, here are decompositions:

  • 11 + 938459 = 938470
  • 17 + 938453 = 938470
  • 23 + 938447 = 938470
  • 83 + 938387 = 938470
  • 101 + 938369 = 938470
  • 191 + 938279 = 938470
  • 227 + 938243 = 938470
  • 251 + 938219 = 938470

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 938,470 and was likely granted around 1909.

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

Position in π

The digit sequence 938470 first appears in π at position 900,621 of the decimal expansion (the 900,621ordinal-suffix:st 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.
