Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31530702, here are decompositions:
- 19 + 31530683 = 31530702
- 23 + 31530679 = 31530702
- 41 + 31530661 = 31530702
- 43 + 31530659 = 31530702
- 53 + 31530649 = 31530702
- 59 + 31530643 = 31530702
- 61 + 31530641 = 31530702
- 109 + 31530593 = 31530702
Showing the first eight; more decompositions exist.
