Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 478778, here are decompositions:

31 + 478747 = 478778
37 + 478741 = 478778
67 + 478711 = 478778
127 + 478651 = 478778
151 + 478627 = 478778
199 + 478579 = 478778
337 + 478441 = 478778
367 + 478411 = 478778

Showing the first eight; more decompositions exist.
