Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1042146, here are decompositions:

5 + 1042141 = 1042146
13 + 1042133 = 1042146
23 + 1042123 = 1042146
37 + 1042109 = 1042146
43 + 1042103 = 1042146
47 + 1042099 = 1042146
59 + 1042087 = 1042146
103 + 1042043 = 1042146

Showing the first eight; more decompositions exist.
