Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 64218, here are decompositions:
- 29 + 64189 = 64218
- 31 + 64187 = 64218
- 47 + 64171 = 64218
- 61 + 64157 = 64218
- 67 + 64151 = 64218
- 109 + 64109 = 64218
- 127 + 64091 = 64218
- 137 + 64081 = 64218
Showing the first eight; more decompositions exist.
