Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31537074, here are decompositions:
- 31 + 31537043 = 31537074
- 47 + 31537027 = 31537074
- 71 + 31537003 = 31537074
- 73 + 31537001 = 31537074
- 83 + 31536991 = 31537074
- 131 + 31536943 = 31537074
- 137 + 31536937 = 31537074
- 157 + 31536917 = 31537074
Showing the first eight; more decompositions exist.
