Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31534770, here are decompositions:
- 13 + 31534757 = 31534770
- 17 + 31534753 = 31534770
- 19 + 31534751 = 31534770
- 31 + 31534739 = 31534770
- 41 + 31534729 = 31534770
- 61 + 31534709 = 31534770
- 79 + 31534691 = 31534770
- 101 + 31534669 = 31534770
Showing the first eight; more decompositions exist.
