Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 513744, here are decompositions:
- 5 + 513739 = 513744
- 13 + 513731 = 513744
- 17 + 513727 = 513744
- 47 + 513697 = 513744
- 53 + 513691 = 513744
- 61 + 513683 = 513744
- 71 + 513673 = 513744
- 103 + 513641 = 513744
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 513,744 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 513744 first appears in π at position 313,483 of the decimal expansion (the 313,483ordinal-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.
