Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1042078, here are decompositions:

347 + 1041731 = 1042078
461 + 1041617 = 1042078
617 + 1041461 = 1042078
761 + 1041317 = 1042078
797 + 1041281 = 1042078
809 + 1041269 = 1042078
839 + 1041239 = 1042078
857 + 1041221 = 1042078

Showing the first eight; more decompositions exist.
