Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 65008, here are decompositions:
- 5 + 65003 = 65008
- 11 + 64997 = 65008
- 71 + 64937 = 65008
- 89 + 64919 = 65008
- 107 + 64901 = 65008
- 131 + 64877 = 65008
- 137 + 64871 = 65008
- 191 + 64817 = 65008
Showing the first eight; more decompositions exist.
