Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1045170, here are decompositions:

13 + 1045157 = 1045170
17 + 1045153 = 1045170
19 + 1045151 = 1045170
41 + 1045129 = 1045170
47 + 1045123 = 1045170
53 + 1045117 = 1045170
59 + 1045111 = 1045170
89 + 1045081 = 1045170

Showing the first eight; more decompositions exist.
