Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8642462, here are decompositions:
- 13 + 8642449 = 8642462
- 79 + 8642383 = 8642462
- 181 + 8642281 = 8642462
- 571 + 8641891 = 8642462
- 643 + 8641819 = 8642462
- 811 + 8641651 = 8642462
- 859 + 8641603 = 8642462
- 919 + 8641543 = 8642462
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 8,642,462 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 8642462 first appears in π at position 748,662 of the decimal expansion (the 748,662ordinal-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.
