Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 509400, here are decompositions:
- 7 + 509393 = 509400
- 11 + 509389 = 509400
- 37 + 509363 = 509400
- 41 + 509359 = 509400
- 71 + 509329 = 509400
- 83 + 509317 = 509400
- 103 + 509297 = 509400
- 107 + 509293 = 509400
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 509,400 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 509400 first appears in π at position 343,188 of the decimal expansion (the 343,188ordinal-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.
