Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 949778, here are decompositions:

7 + 949771 = 949778
19 + 949759 = 949778
79 + 949699 = 949778
127 + 949651 = 949778
157 + 949621 = 949778
211 + 949567 = 949778
307 + 949471 = 949778
337 + 949441 = 949778

Showing the first eight; more decompositions exist.
