Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31537360, here are decompositions:
- 47 + 31537313 = 31537360
- 53 + 31537307 = 31537360
- 89 + 31537271 = 31537360
- 131 + 31537229 = 31537360
- 137 + 31537223 = 31537360
- 227 + 31537133 = 31537360
- 233 + 31537127 = 31537360
- 263 + 31537097 = 31537360
Showing the first eight; more decompositions exist.
