Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 981974, here are decompositions:

13 + 981961 = 981974
61 + 981913 = 981974
151 + 981823 = 981974
157 + 981817 = 981974
163 + 981811 = 981974
271 + 981703 = 981974
277 + 981697 = 981974
283 + 981691 = 981974

Showing the first eight; more decompositions exist.
