Also seen as
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 30678, here are decompositions:
- 7 + 30671 = 30678
- 17 + 30661 = 30678
- 29 + 30649 = 30678
- 41 + 30637 = 30678
- 47 + 30631 = 30678
- 101 + 30577 = 30678
- 139 + 30539 = 30678
- 149 + 30529 = 30678
Showing the first eight; more decompositions exist.
