Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 30956, here are decompositions:

7 + 30949 = 30956
19 + 30937 = 30956
97 + 30859 = 30956
103 + 30853 = 30956
127 + 30829 = 30956
139 + 30817 = 30956
193 + 30763 = 30956
199 + 30757 = 30956

Showing the first eight; more decompositions exist.
