Goldbach decomposition

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.
