Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 513370, here are decompositions:
- 3 + 513367 = 513370
- 17 + 513353 = 513370
- 23 + 513347 = 513370
- 29 + 513341 = 513370
- 59 + 513311 = 513370
- 101 + 513269 = 513370
- 113 + 513257 = 513370
- 131 + 513239 = 513370
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 513,370 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 513370 first appears in π at position 41,643 of the decimal expansion (the 41,643ordinal-suffix:rd 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.
