Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1045190, here are decompositions:

7 + 1045183 = 1045190
37 + 1045153 = 1045190
61 + 1045129 = 1045190
67 + 1045123 = 1045190
73 + 1045117 = 1045190
79 + 1045111 = 1045190
109 + 1045081 = 1045190
127 + 1045063 = 1045190

Showing the first eight; more decompositions exist.
