Also seen as
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 64764, here are decompositions:
- 17 + 64747 = 64764
- 47 + 64717 = 64764
- 71 + 64693 = 64764
- 97 + 64667 = 64764
- 101 + 64663 = 64764
- 103 + 64661 = 64764
- 131 + 64633 = 64764
- 137 + 64627 = 64764
Showing the first eight; more decompositions exist.
