Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1045240, here are decompositions:

3 + 1045237 = 1045240
11 + 1045229 = 1045240
17 + 1045223 = 1045240
41 + 1045199 = 1045240
47 + 1045193 = 1045240
83 + 1045157 = 1045240
89 + 1045151 = 1045240
179 + 1045061 = 1045240

Showing the first eight; more decompositions exist.
