Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1047180, here are decompositions:

7 + 1047173 = 1047180
23 + 1047157 = 1047180
41 + 1047139 = 1047180
47 + 1047133 = 1047180
53 + 1047127 = 1047180
61 + 1047119 = 1047180
73 + 1047107 = 1047180
83 + 1047097 = 1047180

Showing the first eight; more decompositions exist.
