Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1042188, here are decompositions:

5 + 1042183 = 1042188
47 + 1042141 = 1042188
67 + 1042121 = 1042188
79 + 1042109 = 1042188
89 + 1042099 = 1042188
97 + 1042091 = 1042188
101 + 1042087 = 1042188
107 + 1042081 = 1042188

Showing the first eight; more decompositions exist.
