Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31545150, here are decompositions:
- 31 + 31545119 = 31545150
- 53 + 31545097 = 31545150
- 59 + 31545091 = 31545150
- 67 + 31545083 = 31545150
- 83 + 31545067 = 31545150
- 89 + 31545061 = 31545150
- 101 + 31545049 = 31545150
- 127 + 31545023 = 31545150
Showing the first eight; more decompositions exist.
