Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 513118, here are decompositions:
- 17 + 513101 = 513118
- 59 + 513059 = 513118
- 71 + 513047 = 513118
- 101 + 513017 = 513118
- 191 + 512927 = 513118
- 197 + 512921 = 513118
- 227 + 512891 = 513118
- 269 + 512849 = 513118
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 513,118 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 513118 first appears in π at position 959,780 of the decimal expansion (the 959,780ordinal-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.
