Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1043142, here are decompositions:

11 + 1043131 = 1043142
29 + 1043113 = 1043142
31 + 1043111 = 1043142
53 + 1043089 = 1043142
59 + 1043083 = 1043142
131 + 1043011 = 1043142
181 + 1042961 = 1043142
193 + 1042949 = 1043142

Showing the first eight; more decompositions exist.
