Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31542984, here are decompositions:
- 13 + 31542971 = 31542984
- 17 + 31542967 = 31542984
- 41 + 31542943 = 31542984
- 43 + 31542941 = 31542984
- 47 + 31542937 = 31542984
- 73 + 31542911 = 31542984
- 103 + 31542881 = 31542984
- 107 + 31542877 = 31542984
Showing the first eight; more decompositions exist.
