Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8626464, here are decompositions:
- 5 + 8626459 = 8626464
- 43 + 8626421 = 8626464
- 47 + 8626417 = 8626464
- 73 + 8626391 = 8626464
- 163 + 8626301 = 8626464
- 167 + 8626297 = 8626464
- 181 + 8626283 = 8626464
- 193 + 8626271 = 8626464
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 8,626,464 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 8626464 first appears in π at position 636,956 of the decimal expansion (the 636,956ordinal-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.
