Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 513740, here are decompositions:
- 13 + 513727 = 513740
- 43 + 513697 = 513740
- 61 + 513679 = 513740
- 67 + 513673 = 513740
- 109 + 513631 = 513740
- 211 + 513529 = 513740
- 229 + 513511 = 513740
- 313 + 513427 = 513740
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 513,740 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 513740 first appears in π at position 158,151 of the decimal expansion (the 158,151ordinal-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.
