Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 508816, here are decompositions:
- 5 + 508811 = 508816
- 17 + 508799 = 508816
- 89 + 508727 = 508816
- 107 + 508709 = 508816
- 173 + 508643 = 508816
- 179 + 508637 = 508816
- 197 + 508619 = 508816
- 233 + 508583 = 508816
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 508,816 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 508816 first appears in π at position 452,192 of the decimal expansion (the 452,192ordinal-suffix:nd 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.
