Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31537710, here are decompositions:
- 19 + 31537691 = 31537710
- 23 + 31537687 = 31537710
- 79 + 31537631 = 31537710
- 101 + 31537609 = 31537710
- 107 + 31537603 = 31537710
- 137 + 31537573 = 31537710
- 151 + 31537559 = 31537710
- 163 + 31537547 = 31537710
Showing the first eight; more decompositions exist.
