Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 513246, here are decompositions:
- 7 + 513239 = 513246
- 43 + 513203 = 513246
- 73 + 513173 = 513246
- 79 + 513167 = 513246
- 89 + 513157 = 513246
- 109 + 513137 = 513246
- 137 + 513109 = 513246
- 163 + 513083 = 513246
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 513,246 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 513246 first appears in π at position 149,880 of the decimal expansion (the 149,880ordinal-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.
