Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31530202, here are decompositions:
- 5 + 31530197 = 31530202
- 29 + 31530173 = 31530202
- 59 + 31530143 = 31530202
- 173 + 31530029 = 31530202
- 233 + 31529969 = 31530202
- 269 + 31529933 = 31530202
- 311 + 31529891 = 31530202
- 359 + 31529843 = 31530202
Showing the first eight; more decompositions exist.
