Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 512516, here are decompositions:
- 13 + 512503 = 512516
- 19 + 512497 = 512516
- 73 + 512443 = 512516
- 97 + 512419 = 512516
- 127 + 512389 = 512516
- 163 + 512353 = 512516
- 229 + 512287 = 512516
- 349 + 512167 = 512516
Showing the first eight; more decompositions exist.

This number falls in the range of US utility patent numbers. If it's a patent, it would be issued as US 512,516 and was likely granted around 1893.
Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.
The digit sequence 512516 first appears in π at position 974,235 of the decimal expansion (the 974,235ordinal-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.
