Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 64528, here are decompositions:
- 29 + 64499 = 64528
- 89 + 64439 = 64528
- 227 + 64301 = 64528
- 257 + 64271 = 64528
- 311 + 64217 = 64528
- 419 + 64109 = 64528
- 461 + 64067 = 64528
- 491 + 64037 = 64528
Showing the first eight; more decompositions exist.
