Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31537226, here are decompositions:
- 3 + 31537223 = 31537226
- 73 + 31537153 = 31537226
- 79 + 31537147 = 31537226
- 139 + 31537087 = 31537226
- 199 + 31537027 = 31537226
- 223 + 31537003 = 31537226
- 283 + 31536943 = 31537226
- 379 + 31536847 = 31537226
Showing the first eight; more decompositions exist.
