Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 509124, here are decompositions:
- 23 + 509101 = 509124
- 37 + 509087 = 509124
- 53 + 509071 = 509124
- 61 + 509063 = 509124
- 71 + 509053 = 509124
- 97 + 509027 = 509124
- 101 + 509023 = 509124
- 137 + 508987 = 509124
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 509,124 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 509124 first appears in π at position 498,223 of the decimal expansion (the 498,223ordinal-suffix:rd 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.
