Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 490750, here are decompositions:

  • 17 + 490733 = 490750
  • 53 + 490697 = 490750
  • 89 + 490661 = 490750
  • 107 + 490643 = 490750
  • 131 + 490619 = 490750
  • 173 + 490577 = 490750
  • 179 + 490571 = 490750
  • 191 + 490559 = 490750

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 490,750 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 490750 first appears in π at position 330,977 of the decimal expansion (the 330,977ordinal-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.
