Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 39778, here are decompositions:
- 17 + 39761 = 39778
- 29 + 39749 = 39778
- 59 + 39719 = 39778
- 107 + 39671 = 39778
- 197 + 39581 = 39778
- 227 + 39551 = 39778
- 257 + 39521 = 39778
- 269 + 39509 = 39778
Showing the first eight; more decompositions exist.
