Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 64976, here are decompositions:
- 7 + 64969 = 64976
- 97 + 64879 = 64976
- 127 + 64849 = 64976
- 193 + 64783 = 64976
- 229 + 64747 = 64976
- 283 + 64693 = 64976
- 313 + 64663 = 64976
- 349 + 64627 = 64976
Showing the first eight; more decompositions exist.
