Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 64650, here are decompositions:
- 17 + 64633 = 64650
- 23 + 64627 = 64650
- 29 + 64621 = 64650
- 37 + 64613 = 64650
- 41 + 64609 = 64650
- 59 + 64591 = 64650
- 71 + 64579 = 64650
- 73 + 64577 = 64650
Showing the first eight; more decompositions exist.
