Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31543924, here are decompositions:
- 11 + 31543913 = 31543924
- 17 + 31543907 = 31543924
- 47 + 31543877 = 31543924
- 53 + 31543871 = 31543924
- 107 + 31543817 = 31543924
- 173 + 31543751 = 31543924
- 227 + 31543697 = 31543924
- 233 + 31543691 = 31543924
Showing the first eight; more decompositions exist.
