Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 470830, here are decompositions:

  • 11 + 470819 = 470830
  • 47 + 470783 = 470830
  • 167 + 470663 = 470830
  • 179 + 470651 = 470830
  • 233 + 470597 = 470830
  • 251 + 470579 = 470830
  • 317 + 470513 = 470830
  • 359 + 470471 = 470830

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 470,830 and was likely granted around 1891.

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

Position in π

The digit sequence 470830 first appears in π at position 621,070 of the decimal expansion (the 621,070ordinal-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.
