Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1047216, here are decompositions:

17 + 1047199 = 1047216
19 + 1047197 = 1047216
43 + 1047173 = 1047216
59 + 1047157 = 1047216
83 + 1047133 = 1047216
89 + 1047127 = 1047216
97 + 1047119 = 1047216
109 + 1047107 = 1047216

Showing the first eight; more decompositions exist.
