Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31543074, here are decompositions:
- 5 + 31543069 = 31543074
- 7 + 31543067 = 31543074
- 83 + 31542991 = 31543074
- 103 + 31542971 = 31543074
- 107 + 31542967 = 31543074
- 131 + 31542943 = 31543074
- 137 + 31542937 = 31543074
- 163 + 31542911 = 31543074
Showing the first eight; more decompositions exist.
