Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 64966, here are decompositions:
- 29 + 64937 = 64966
- 47 + 64919 = 64966
- 89 + 64877 = 64966
- 113 + 64853 = 64966
- 149 + 64817 = 64966
- 173 + 64793 = 64966
- 257 + 64709 = 64966
- 353 + 64613 = 64966
Showing the first eight; more decompositions exist.
