Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8722504, here are decompositions:
- 5 + 8722499 = 8722504
- 113 + 8722391 = 8722504
- 137 + 8722367 = 8722504
- 173 + 8722331 = 8722504
- 281 + 8722223 = 8722504
- 293 + 8722211 = 8722504
- 311 + 8722193 = 8722504
- 317 + 8722187 = 8722504
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 8,722,504 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 8722504 first appears in π at position 856,298 of the decimal expansion (the 856,298ordinal-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.
