Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8624228, here are decompositions:
- 7 + 8624221 = 8624228
- 37 + 8624191 = 8624228
- 97 + 8624131 = 8624228
- 127 + 8624101 = 8624228
- 211 + 8624017 = 8624228
- 331 + 8623897 = 8624228
- 397 + 8623831 = 8624228
- 421 + 8623807 = 8624228
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 8,624,228 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 8624228 first appears in π at position 118,433 of the decimal expansion (the 118,433ordinal-suffix:rd 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.
