Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 508440, here are decompositions:
- 7 + 508433 = 508440
- 47 + 508393 = 508440
- 67 + 508373 = 508440
- 73 + 508367 = 508440
- 109 + 508331 = 508440
- 113 + 508327 = 508440
- 139 + 508301 = 508440
- 167 + 508273 = 508440
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 508,440 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 508440 first appears in π at position 757,743 of the decimal expansion (the 757,743ordinal-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.
