Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 513624, here are decompositions:
- 31 + 513593 = 513624
- 113 + 513511 = 513624
- 151 + 513473 = 513624
- 193 + 513431 = 513624
- 197 + 513427 = 513624
- 227 + 513397 = 513624
- 257 + 513367 = 513624
- 271 + 513353 = 513624
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 513,624 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 513624 first appears in π at position 910,847 of the decimal expansion (the 910,847ordinal-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.
