Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 109778, here are decompositions:
- 37 + 109741 = 109778
- 61 + 109717 = 109778
- 139 + 109639 = 109778
- 157 + 109621 = 109778
- 181 + 109597 = 109778
- 199 + 109579 = 109778
- 211 + 109567 = 109778
- 241 + 109537 = 109778
Showing the first eight; more decompositions exist.
