Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 513678, here are decompositions:
- 5 + 513673 = 513678
- 29 + 513649 = 513678
- 37 + 513641 = 513678
- 47 + 513631 = 513678
- 149 + 513529 = 513678
- 167 + 513511 = 513678
- 197 + 513481 = 513678
- 199 + 513479 = 513678
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 513,678 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 513678 first appears in π at position 788,531 of the decimal expansion (the 788,531ordinal-suffix:st 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.
