Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8642104, here are decompositions:
- 5 + 8642099 = 8642104
- 41 + 8642063 = 8642104
- 47 + 8642057 = 8642104
- 71 + 8642033 = 8642104
- 101 + 8642003 = 8642104
- 113 + 8641991 = 8642104
- 431 + 8641673 = 8642104
- 461 + 8641643 = 8642104
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 8,642,104 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 8642104 first appears in π at position 471,721 of the decimal expansion (the 471,721ordinal-suffix:st 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.
