Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1045188, here are decompositions:

5 + 1045183 = 1045188
31 + 1045157 = 1045188
37 + 1045151 = 1045188
59 + 1045129 = 1045188
71 + 1045117 = 1045188
107 + 1045081 = 1045188
127 + 1045061 = 1045188
167 + 1045021 = 1045188

Showing the first eight; more decompositions exist.
