Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 515000, here are decompositions:

61 + 514939 = 515000
67 + 514933 = 515000
97 + 514903 = 515000
127 + 514873 = 515000
181 + 514819 = 515000
331 + 514669 = 515000
349 + 514651 = 515000
379 + 514621 = 515000

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 515,000 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 515000 first appears in π at position 542,999 of the decimal expansion (the 542,999ordinal-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.
