Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 513772, here are decompositions:
- 3 + 513769 = 513772
- 5 + 513767 = 513772
- 11 + 513761 = 513772
- 23 + 513749 = 513772
- 41 + 513731 = 513772
- 53 + 513719 = 513772
- 89 + 513683 = 513772
- 131 + 513641 = 513772
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 513,772 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 513772 first appears in π at position 510,629 of the decimal expansion (the 510,629ordinal-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.
