Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1020140, here are decompositions:

3 + 1020137 = 1020140
31 + 1020109 = 1020140
61 + 1020079 = 1020140
97 + 1020043 = 1020140
103 + 1020037 = 1020140
127 + 1020013 = 1020140
139 + 1020001 = 1020140
241 + 1019899 = 1020140

Showing the first eight; more decompositions exist.
