Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1015142, here are decompositions:

3 + 1015139 = 1015142
19 + 1015123 = 1015142
61 + 1015081 = 1015142
103 + 1015039 = 1015142
379 + 1014763 = 1015142
421 + 1014721 = 1015142
571 + 1014571 = 1015142
673 + 1014469 = 1015142

Showing the first eight; more decompositions exist.
