Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 513672, here are decompositions:
- 23 + 513649 = 513672
- 31 + 513641 = 513672
- 41 + 513631 = 513672
- 79 + 513593 = 513672
- 139 + 513533 = 513672
- 163 + 513509 = 513672
- 191 + 513481 = 513672
- 193 + 513479 = 513672
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 513,672 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 513672 first appears in π at position 531,154 of the decimal expansion (the 531,154ordinal-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.
