Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1047120, here are decompositions:

13 + 1047107 = 1047120
23 + 1047097 = 1047120
31 + 1047089 = 1047120
43 + 1047077 = 1047120
59 + 1047061 = 1047120
79 + 1047041 = 1047120
89 + 1047031 = 1047120
127 + 1046993 = 1047120

Showing the first eight; more decompositions exist.
