Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 508642, here are decompositions:
- 5 + 508637 = 508642
- 23 + 508619 = 508642
- 59 + 508583 = 508642
- 83 + 508559 = 508642
- 191 + 508451 = 508642
- 269 + 508373 = 508642
- 293 + 508349 = 508642
- 311 + 508331 = 508642
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 508,642 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 508642 first appears in π at position 540,690 of the decimal expansion (the 540,690ordinal-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.
