Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 548820, here are decompositions:

  • 29 + 548791 = 548820
  • 37 + 548783 = 548820
  • 59 + 548761 = 548820
  • 67 + 548753 = 548820
  • 71 + 548749 = 548820
  • 101 + 548719 = 548820
  • 113 + 548707 = 548820
  • 127 + 548693 = 548820

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 548,820 and was likely granted around 1895.

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

Position in π

The digit sequence 548820 first appears in π at position 370 of the decimal expansion (the 370ordinal-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.
