Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 490078, here are decompositions:

  • 47 + 490031 = 490078
  • 59 + 490019 = 490078
  • 89 + 489989 = 490078
  • 101 + 489977 = 490078
  • 137 + 489941 = 490078
  • 167 + 489911 = 490078
  • 191 + 489887 = 490078
  • 227 + 489851 = 490078

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 490,078 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 490078 first appears in π at position 105,082 of the decimal expansion (the 105,082ordinal-suffix:nd 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.
