Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31545036, here are decompositions:
- 13 + 31545023 = 31545036
- 67 + 31544969 = 31545036
- 73 + 31544963 = 31545036
- 113 + 31544923 = 31545036
- 137 + 31544899 = 31545036
- 157 + 31544879 = 31545036
- 179 + 31544857 = 31545036
- 277 + 31544759 = 31545036
Showing the first eight; more decompositions exist.
