Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 508240, here are decompositions:
- 3 + 508237 = 508240
- 11 + 508229 = 508240
- 17 + 508223 = 508240
- 53 + 508187 = 508240
- 137 + 508103 = 508240
- 149 + 508091 = 508240
- 167 + 508073 = 508240
- 269 + 507971 = 508240
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 508,240 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 508240 first appears in π at position 639,246 of the decimal expansion (the 639,246ordinal-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.
