Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1048478, here are decompositions:

31 + 1048447 = 1048478
349 + 1048129 = 1048478
499 + 1047979 = 1048478
619 + 1047859 = 1048478
727 + 1047751 = 1048478
757 + 1047721 = 1048478
787 + 1047691 = 1048478
811 + 1047667 = 1048478

Showing the first eight; more decompositions exist.
