Also seen as
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 30648, here are decompositions:
- 5 + 30643 = 30648
- 11 + 30637 = 30648
- 17 + 30631 = 30648
- 71 + 30577 = 30648
- 89 + 30559 = 30648
- 109 + 30539 = 30648
- 131 + 30517 = 30648
- 139 + 30509 = 30648
Showing the first eight; more decompositions exist.
