Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8642460, here are decompositions:
- 7 + 8642453 = 8642460
- 11 + 8642449 = 8642460
- 31 + 8642429 = 8642460
- 131 + 8642329 = 8642460
- 157 + 8642303 = 8642460
- 179 + 8642281 = 8642460
- 223 + 8642237 = 8642460
- 263 + 8642197 = 8642460
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 8,642,460 and was likely granted around 2014.
Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.
The digit sequence 8642460 first appears in π at position 624,262 of the decimal expansion (the 624,262ordinal-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.
