Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8749104, here are decompositions:
- 17 + 8749087 = 8749104
- 97 + 8749007 = 8749104
- 103 + 8749001 = 8749104
- 113 + 8748991 = 8749104
- 131 + 8748973 = 8749104
- 151 + 8748953 = 8749104
- 211 + 8748893 = 8749104
- 223 + 8748881 = 8749104
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 8,749,104 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 8749104 first appears in π at position 137,297 of the decimal expansion (the 137,297ordinal-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.
