Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 977946, here are decompositions:

19 + 977927 = 977946
23 + 977923 = 977946
97 + 977849 = 977946
127 + 977819 = 977946
199 + 977747 = 977946
223 + 977723 = 977946
227 + 977719 = 977946
317 + 977629 = 977946

Showing the first eight; more decompositions exist.
