Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 64918, here are decompositions:
- 17 + 64901 = 64918
- 41 + 64877 = 64918
- 47 + 64871 = 64918
- 101 + 64817 = 64918
- 107 + 64811 = 64918
- 137 + 64781 = 64918
- 239 + 64679 = 64918
- 251 + 64667 = 64918
Showing the first eight; more decompositions exist.
