Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8624424, here are decompositions:
- 31 + 8624393 = 8624424
- 41 + 8624383 = 8624424
- 71 + 8624353 = 8624424
- 97 + 8624327 = 8624424
- 101 + 8624323 = 8624424
- 113 + 8624311 = 8624424
- 157 + 8624267 = 8624424
- 173 + 8624251 = 8624424
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 8,624,424 and was likely granted around 2013.
Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.
The digit sequence 8624424 first appears in π at position 184,145 of the decimal expansion (the 184,145ordinal-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.
