Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 986142, here are decompositions:

5 + 986137 = 986142
11 + 986131 = 986142
29 + 986113 = 986142
41 + 986101 = 986142
71 + 986071 = 986142
89 + 986053 = 986142
149 + 985993 = 986142
151 + 985991 = 986142

Showing the first eight; more decompositions exist.
