Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 519890, here are decompositions:

  • 73 + 519817 = 519890
  • 97 + 519793 = 519890
  • 103 + 519787 = 519890
  • 157 + 519733 = 519890
  • 199 + 519691 = 519890
  • 223 + 519667 = 519890
  • 271 + 519619 = 519890
  • 313 + 519577 = 519890

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 519,890 and was likely granted around 1894.

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

Position in π

The digit sequence 519890 first appears in π at position 76,251 of the decimal expansion (the 76,251ordinal-suffix:st 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.
