Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 513142, here are decompositions:
- 5 + 513137 = 513142
- 11 + 513131 = 513142
- 41 + 513101 = 513142
- 59 + 513083 = 513142
- 83 + 513059 = 513142
- 89 + 513053 = 513142
- 101 + 513041 = 513142
- 239 + 512903 = 513142
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 513,142 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 513142 first appears in π at position 748,075 of the decimal expansion (the 748,075ordinal-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.
