Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 64564, here are decompositions:
- 11 + 64553 = 64564
- 113 + 64451 = 64564
- 131 + 64433 = 64564
- 191 + 64373 = 64564
- 263 + 64301 = 64564
- 281 + 64283 = 64564
- 293 + 64271 = 64564
- 347 + 64217 = 64564
Showing the first eight; more decompositions exist.
