Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 490046, here are decompositions:

  • 13 + 490033 = 490046
  • 43 + 490003 = 490046
  • 103 + 489943 = 490046
  • 199 + 489847 = 490046
  • 223 + 489823 = 490046
  • 229 + 489817 = 490046
  • 313 + 489733 = 490046
  • 367 + 489679 = 490046

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 490,046 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 490046 first appears in π at position 547,632 of the decimal expansion (the 547,632ordinal-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.
