Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 508428, here are decompositions:
- 61 + 508367 = 508428
- 79 + 508349 = 508428
- 97 + 508331 = 508428
- 101 + 508327 = 508428
- 127 + 508301 = 508428
- 131 + 508297 = 508428
- 157 + 508271 = 508428
- 191 + 508237 = 508428
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 508,428 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 508428 first appears in π at position 951,695 of the decimal expansion (the 951,695ordinal-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.
