Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 30962, here are decompositions:

13 + 30949 = 30962
31 + 30931 = 30962
103 + 30859 = 30962
109 + 30853 = 30962
181 + 30781 = 30962
199 + 30763 = 30962
313 + 30649 = 30962
331 + 30631 = 30962

Showing the first eight; more decompositions exist.
