Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31537094, here are decompositions:
- 7 + 31537087 = 31537094
- 67 + 31537027 = 31537094
- 103 + 31536991 = 31537094
- 151 + 31536943 = 31537094
- 157 + 31536937 = 31537094
- 223 + 31536871 = 31537094
- 271 + 31536823 = 31537094
- 397 + 31536697 = 31537094
Showing the first eight; more decompositions exist.
