Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 64788, here are decompositions:
- 5 + 64783 = 64788
- 7 + 64781 = 64788
- 41 + 64747 = 64788
- 71 + 64717 = 64788
- 79 + 64709 = 64788
- 109 + 64679 = 64788
- 127 + 64661 = 64788
- 167 + 64621 = 64788
Showing the first eight; more decompositions exist.
