Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 974778, here are decompositions:

5 + 974773 = 974778
17 + 974761 = 974778
29 + 974749 = 974778
31 + 974747 = 974778
41 + 974737 = 974778
67 + 974711 = 974778
71 + 974707 = 974778
127 + 974651 = 974778

Showing the first eight; more decompositions exist.
