Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31534788, here are decompositions:
- 31 + 31534757 = 31534788
- 37 + 31534751 = 31534788
- 59 + 31534729 = 31534788
- 79 + 31534709 = 31534788
- 97 + 31534691 = 31534788
- 137 + 31534651 = 31534788
- 151 + 31534637 = 31534788
- 157 + 31534631 = 31534788
Showing the first eight; more decompositions exist.
