Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 39688, here are decompositions:
- 17 + 39671 = 39688
- 29 + 39659 = 39688
- 107 + 39581 = 39688
- 137 + 39551 = 39688
- 167 + 39521 = 39688
- 179 + 39509 = 39688
- 227 + 39461 = 39688
- 269 + 39419 = 39688
Showing the first eight; more decompositions exist.
