Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 64576, here are decompositions:
- 23 + 64553 = 64576
- 137 + 64439 = 64576
- 173 + 64403 = 64576
- 257 + 64319 = 64576
- 293 + 64283 = 64576
- 353 + 64223 = 64576
- 359 + 64217 = 64576
- 389 + 64187 = 64576
Showing the first eight; more decompositions exist.
