Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 30788, here are decompositions:
- 7 + 30781 = 30788
- 31 + 30757 = 30788
- 61 + 30727 = 30788
- 127 + 30661 = 30788
- 139 + 30649 = 30788
- 151 + 30637 = 30788
- 157 + 30631 = 30788
- 211 + 30577 = 30788
Showing the first eight; more decompositions exist.
