Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31530748, here are decompositions:
- 47 + 31530701 = 31530748
- 89 + 31530659 = 31530748
- 107 + 31530641 = 31530748
- 131 + 31530617 = 31530748
- 251 + 31530497 = 31530748
- 269 + 31530479 = 31530748
- 311 + 31530437 = 31530748
- 401 + 31530347 = 31530748
Showing the first eight; more decompositions exist.
