Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8624478, here are decompositions:
- 19 + 8624459 = 8624478
- 29 + 8624449 = 8624478
- 151 + 8624327 = 8624478
- 167 + 8624311 = 8624478
- 211 + 8624267 = 8624478
- 227 + 8624251 = 8624478
- 229 + 8624249 = 8624478
- 241 + 8624237 = 8624478
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 8,624,478 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 8624478 first appears in π at position 45,962 of the decimal expansion (the 45,962ordinal-suffix:nd 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.
