Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 30642, here are decompositions:

5 + 30637 = 30642
11 + 30631 = 30642
83 + 30559 = 30642
89 + 30553 = 30642
103 + 30539 = 30642
113 + 30529 = 30642
149 + 30493 = 30642
151 + 30491 = 30642

Showing the first eight; more decompositions exist.
