Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 65160, here are decompositions:
- 13 + 65147 = 65160
- 19 + 65141 = 65160
- 31 + 65129 = 65160
- 37 + 65123 = 65160
- 41 + 65119 = 65160
- 59 + 65101 = 65160
- 61 + 65099 = 65160
- 71 + 65089 = 65160
Showing the first eight; more decompositions exist.
