Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31537104, here are decompositions:
- 7 + 31537097 = 31537104
- 17 + 31537087 = 31537104
- 61 + 31537043 = 31537104
- 101 + 31537003 = 31537104
- 103 + 31537001 = 31537104
- 113 + 31536991 = 31537104
- 167 + 31536937 = 31537104
- 233 + 31536871 = 31537104
Showing the first eight; more decompositions exist.
