Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31537008, here are decompositions:
- 5 + 31537003 = 31537008
- 7 + 31537001 = 31537008
- 17 + 31536991 = 31537008
- 71 + 31536937 = 31537008
- 137 + 31536871 = 31537008
- 179 + 31536829 = 31537008
- 277 + 31536731 = 31537008
- 311 + 31536697 = 31537008
Showing the first eight; more decompositions exist.
