Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 513880, here are decompositions:
- 41 + 513839 = 513880
- 113 + 513767 = 513880
- 131 + 513749 = 513880
- 149 + 513731 = 513880
- 197 + 513683 = 513880
- 239 + 513641 = 513880
- 347 + 513533 = 513880
- 401 + 513479 = 513880
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 513,880 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 513880 first appears in π at position 966,896 of the decimal expansion (the 966,896ordinal-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.
