Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 64628, here are decompositions:
- 7 + 64621 = 64628
- 19 + 64609 = 64628
- 37 + 64591 = 64628
- 61 + 64567 = 64628
- 139 + 64489 = 64628
- 229 + 64399 = 64628
- 349 + 64279 = 64628
- 397 + 64231 = 64628
Showing the first eight; more decompositions exist.
