Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1045142, here are decompositions:

13 + 1045129 = 1045142
19 + 1045123 = 1045142
31 + 1045111 = 1045142
61 + 1045081 = 1045142
79 + 1045063 = 1045142
139 + 1045003 = 1045142
211 + 1044931 = 1045142
283 + 1044859 = 1045142

Showing the first eight; more decompositions exist.
