Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 65242, here are decompositions:
- 3 + 65239 = 65242
- 29 + 65213 = 65242
- 59 + 65183 = 65242
- 71 + 65171 = 65242
- 101 + 65141 = 65242
- 113 + 65129 = 65242
- 131 + 65111 = 65242
- 179 + 65063 = 65242
Showing the first eight; more decompositions exist.
