Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 502428, here are decompositions:

  • 7 + 502421 = 502428
  • 19 + 502409 = 502428
  • 89 + 502339 = 502428
  • 107 + 502321 = 502428
  • 127 + 502301 = 502428
  • 151 + 502277 = 502428
  • 167 + 502261 = 502428
  • 181 + 502247 = 502428

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 502,428 and was likely granted around 1893.

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

Position in π

The digit sequence 502428 first appears in π at position 343,867 of the decimal expansion (the 343,867ordinal-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.
