Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8742804, here are decompositions:
- 17 + 8742787 = 8742804
- 127 + 8742677 = 8742804
- 131 + 8742673 = 8742804
- 151 + 8742653 = 8742804
- 167 + 8742637 = 8742804
- 181 + 8742623 = 8742804
- 227 + 8742577 = 8742804
- 233 + 8742571 = 8742804
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 8,742,804 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 8742804 first appears in π at position 443,315 of the decimal expansion (the 443,315ordinal-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.
