Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 513730, here are decompositions:
- 3 + 513727 = 513730
- 11 + 513719 = 513730
- 47 + 513683 = 513730
- 89 + 513641 = 513730
- 137 + 513593 = 513730
- 197 + 513533 = 513730
- 251 + 513479 = 513730
- 257 + 513473 = 513730
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 513,730 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 513730 first appears in π at position 376,249 of the decimal expansion (the 376,249ordinal-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.
