Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31530786, here are decompositions:
- 13 + 31530773 = 31530786
- 73 + 31530713 = 31530786
- 83 + 31530703 = 31530786
- 103 + 31530683 = 31530786
- 107 + 31530679 = 31530786
- 127 + 31530659 = 31530786
- 137 + 31530649 = 31530786
- 149 + 31530637 = 31530786
Showing the first eight; more decompositions exist.
