Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1040208, here are decompositions:

5 + 1040203 = 1040208
17 + 1040191 = 1040208
19 + 1040189 = 1040208
41 + 1040167 = 1040208
47 + 1040161 = 1040208
67 + 1040141 = 1040208
89 + 1040119 = 1040208
107 + 1040101 = 1040208

Showing the first eight; more decompositions exist.
