Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31542804, here are decompositions:
- 5 + 31542799 = 31542804
- 17 + 31542787 = 31542804
- 37 + 31542767 = 31542804
- 101 + 31542703 = 31542804
- 107 + 31542697 = 31542804
- 127 + 31542677 = 31542804
- 173 + 31542631 = 31542804
- 191 + 31542613 = 31542804
Showing the first eight; more decompositions exist.
