Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31826, here are decompositions:
- 97 + 31729 = 31826
- 103 + 31723 = 31826
- 127 + 31699 = 31826
- 139 + 31687 = 31826
- 163 + 31663 = 31826
- 199 + 31627 = 31826
- 283 + 31543 = 31826
- 313 + 31513 = 31826
Showing the first eight; more decompositions exist.
