Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31543116, here are decompositions:
- 13 + 31543103 = 31543116
- 37 + 31543079 = 31543116
- 47 + 31543069 = 31543116
- 97 + 31543019 = 31543116
- 107 + 31543009 = 31543116
- 149 + 31542967 = 31543116
- 167 + 31542949 = 31543116
- 173 + 31542943 = 31543116
Showing the first eight; more decompositions exist.
