Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1047646, here are decompositions:

59 + 1047587 = 1047646
107 + 1047539 = 1047646
113 + 1047533 = 1047646
167 + 1047479 = 1047646
179 + 1047467 = 1047646
227 + 1047419 = 1047646
449 + 1047197 = 1047646
557 + 1047089 = 1047646

Showing the first eight; more decompositions exist.
