Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 39748, here are decompositions:
- 29 + 39719 = 39748
- 89 + 39659 = 39748
- 167 + 39581 = 39748
- 179 + 39569 = 39748
- 197 + 39551 = 39748
- 227 + 39521 = 39748
- 239 + 39509 = 39748
- 389 + 39359 = 39748
Showing the first eight; more decompositions exist.
