Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 30778, here are decompositions:
- 5 + 30773 = 30778
- 71 + 30707 = 30778
- 89 + 30689 = 30778
- 101 + 30677 = 30778
- 107 + 30671 = 30778
- 239 + 30539 = 30778
- 269 + 30509 = 30778
- 281 + 30497 = 30778
Showing the first eight; more decompositions exist.
