Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31530652, here are decompositions:
- 3 + 31530649 = 31530652
- 11 + 31530641 = 31530652
- 59 + 31530593 = 31530652
- 173 + 31530479 = 31530652
- 233 + 31530419 = 31530652
- 269 + 31530383 = 31530652
- 311 + 31530341 = 31530652
- 359 + 31530293 = 31530652
Showing the first eight; more decompositions exist.
