Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31537064, here are decompositions:
- 37 + 31537027 = 31537064
- 61 + 31537003 = 31537064
- 73 + 31536991 = 31537064
- 127 + 31536937 = 31537064
- 193 + 31536871 = 31537064
- 241 + 31536823 = 31537064
- 271 + 31536793 = 31537064
- 331 + 31536733 = 31537064
Showing the first eight; more decompositions exist.
