Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 65238, here are decompositions:
- 59 + 65179 = 65238
- 67 + 65171 = 65238
- 71 + 65167 = 65238
- 97 + 65141 = 65238
- 109 + 65129 = 65238
- 127 + 65111 = 65238
- 137 + 65101 = 65238
- 139 + 65099 = 65238
Showing the first eight; more decompositions exist.
