Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 478730, here are decompositions:

  • 3 + 478727 = 478730
  • 19 + 478711 = 478730
  • 79 + 478651 = 478730
  • 103 + 478627 = 478730
  • 127 + 478603 = 478730
  • 151 + 478579 = 478730
  • 157 + 478573 = 478730
  • 199 + 478531 = 478730

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 478,730 and was likely granted around 1892.

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

Position in π

The digit sequence 478730 first appears in π at position 819,459 of the decimal expansion (the 819,459ordinal-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.
