Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 513750, here are decompositions:
- 11 + 513739 = 513750
- 19 + 513731 = 513750
- 23 + 513727 = 513750
- 31 + 513719 = 513750
- 53 + 513697 = 513750
- 59 + 513691 = 513750
- 67 + 513683 = 513750
- 71 + 513679 = 513750
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 513,750 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 513750 first appears in π at position 919,406 of the decimal expansion (the 919,406ordinal-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.
