Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31530600, here are decompositions:
- 7 + 31530593 = 31530600
- 11 + 31530589 = 31530600
- 29 + 31530571 = 31530600
- 103 + 31530497 = 31530600
- 113 + 31530487 = 31530600
- 149 + 31530451 = 31530600
- 163 + 31530437 = 31530600
- 181 + 31530419 = 31530600
Showing the first eight; more decompositions exist.
