Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 507642, here are decompositions:
- 11 + 507631 = 507642
- 43 + 507599 = 507642
- 53 + 507589 = 507642
- 71 + 507571 = 507642
- 139 + 507503 = 507642
- 151 + 507491 = 507642
- 181 + 507461 = 507642
- 211 + 507431 = 507642
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 507,642 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 507642 first appears in π at position 254,689 of the decimal expansion (the 254,689ordinal-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.
