Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 508242, here are decompositions:
- 5 + 508237 = 508242
- 13 + 508229 = 508242
- 19 + 508223 = 508242
- 29 + 508213 = 508242
- 71 + 508171 = 508242
- 83 + 508159 = 508242
- 113 + 508129 = 508242
- 139 + 508103 = 508242
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 508,242 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 508242 first appears in π at position 440,149 of the decimal expansion (the 440,149ordinal-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.
