Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8611564, here are decompositions:
- 41 + 8611523 = 8611564
- 131 + 8611433 = 8611564
- 233 + 8611331 = 8611564
- 257 + 8611307 = 8611564
- 263 + 8611301 = 8611564
- 281 + 8611283 = 8611564
- 317 + 8611247 = 8611564
- 383 + 8611181 = 8611564
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 8,611,564 and was likely granted around 2013.
Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.
