Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 30974, here are decompositions:

3 + 30971 = 30974
37 + 30937 = 30974
43 + 30931 = 30974
103 + 30871 = 30974
157 + 30817 = 30974
193 + 30781 = 30974
211 + 30763 = 30974
271 + 30703 = 30974

Showing the first eight; more decompositions exist.
