Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1047578, here are decompositions:

19 + 1047559 = 1047578
67 + 1047511 = 1047578
79 + 1047499 = 1047578
109 + 1047469 = 1047578
199 + 1047379 = 1047578
211 + 1047367 = 1047578
271 + 1047307 = 1047578
307 + 1047271 = 1047578

Showing the first eight; more decompositions exist.
