Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 470920, here are decompositions:

  • 17 + 470903 = 470920
  • 29 + 470891 = 470920
  • 53 + 470867 = 470920
  • 83 + 470837 = 470920
  • 89 + 470831 = 470920
  • 101 + 470819 = 470920
  • 137 + 470783 = 470920
  • 251 + 470669 = 470920

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 470,920 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 470920 first appears in π at position 739,643 of the decimal expansion (the 739,643ordinal-suffix:rd 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.
