Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 513178, here are decompositions:
- 5 + 513173 = 513178
- 11 + 513167 = 513178
- 41 + 513137 = 513178
- 47 + 513131 = 513178
- 131 + 513047 = 513178
- 137 + 513041 = 513178
- 179 + 512999 = 513178
- 251 + 512927 = 513178
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 513,178 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 513178 first appears in π at position 251,837 of the decimal expansion (the 251,837ordinal-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.
