Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 64806, here are decompositions:
- 13 + 64793 = 64806
- 23 + 64783 = 64806
- 43 + 64763 = 64806
- 59 + 64747 = 64806
- 89 + 64717 = 64806
- 97 + 64709 = 64806
- 113 + 64693 = 64806
- 127 + 64679 = 64806
Showing the first eight; more decompositions exist.
