Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1045290, here are decompositions:

13 + 1045277 = 1045290
17 + 1045273 = 1045290
53 + 1045237 = 1045290
61 + 1045229 = 1045290
67 + 1045223 = 1045290
97 + 1045193 = 1045290
107 + 1045183 = 1045290
137 + 1045153 = 1045290

Showing the first eight; more decompositions exist.
