Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 513250, here are decompositions:
- 11 + 513239 = 513250
- 47 + 513203 = 513250
- 83 + 513167 = 513250
- 113 + 513137 = 513250
- 149 + 513101 = 513250
- 167 + 513083 = 513250
- 191 + 513059 = 513250
- 197 + 513053 = 513250
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 513,250 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 513250 first appears in π at position 187,012 of the decimal expansion (the 187,012ordinal-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.
