Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8704040, here are decompositions:
- 13 + 8704027 = 8704040
- 97 + 8703943 = 8704040
- 151 + 8703889 = 8704040
- 181 + 8703859 = 8704040
- 199 + 8703841 = 8704040
- 211 + 8703829 = 8704040
- 223 + 8703817 = 8704040
- 229 + 8703811 = 8704040
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 8,704,040 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 8704040 first appears in π at position 300,207 of the decimal expansion (the 300,207ordinal-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.
