Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1048142, here are decompositions:

3 + 1048139 = 1048142
13 + 1048129 = 1048142
19 + 1048123 = 1048142
79 + 1048063 = 1048142
163 + 1047979 = 1048142
181 + 1047961 = 1048142
283 + 1047859 = 1048142
379 + 1047763 = 1048142

Showing the first eight; more decompositions exist.
