Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31535982, here are decompositions:
- 41 + 31535941 = 31535982
- 43 + 31535939 = 31535982
- 73 + 31535909 = 31535982
- 103 + 31535879 = 31535982
- 151 + 31535831 = 31535982
- 173 + 31535809 = 31535982
- 229 + 31535753 = 31535982
- 241 + 31535741 = 31535982
Showing the first eight; more decompositions exist.
