Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 65212, here are decompositions:
- 29 + 65183 = 65212
- 41 + 65171 = 65212
- 71 + 65141 = 65212
- 83 + 65129 = 65212
- 89 + 65123 = 65212
- 101 + 65111 = 65212
- 113 + 65099 = 65212
- 149 + 65063 = 65212
Showing the first eight; more decompositions exist.
