Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 512624, here are decompositions:
- 3 + 512621 = 512624
- 31 + 512593 = 512624
- 43 + 512581 = 512624
- 103 + 512521 = 512624
- 127 + 512497 = 512624
- 157 + 512467 = 512624
- 181 + 512443 = 512624
- 271 + 512353 = 512624
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 512,624 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 512624 first appears in π at position 389,601 of the decimal expansion (the 389,601ordinal-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.
