Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 64944, here are decompositions:
- 7 + 64937 = 64944
- 17 + 64927 = 64944
- 23 + 64921 = 64944
- 43 + 64901 = 64944
- 53 + 64891 = 64944
- 67 + 64877 = 64944
- 73 + 64871 = 64944
- 127 + 64817 = 64944
Showing the first eight; more decompositions exist.
