Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1030142, here are decompositions:

31 + 1030111 = 1030142
73 + 1030069 = 1030142
103 + 1030039 = 1030142
109 + 1030033 = 1030142
199 + 1029943 = 1030142
283 + 1029859 = 1030142
499 + 1029643 = 1030142
541 + 1029601 = 1030142

Showing the first eight; more decompositions exist.
