Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1047920, here are decompositions:

37 + 1047883 = 1047920
61 + 1047859 = 1047920
79 + 1047841 = 1047920
157 + 1047763 = 1047920
199 + 1047721 = 1047920
229 + 1047691 = 1047920
271 + 1047649 = 1047920
331 + 1047589 = 1047920

Showing the first eight; more decompositions exist.
