Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1042142, here are decompositions:

19 + 1042123 = 1042142
43 + 1042099 = 1042142
61 + 1042081 = 1042142
103 + 1042039 = 1042142
151 + 1041991 = 1042142
181 + 1041961 = 1042142
193 + 1041949 = 1042142
223 + 1041919 = 1042142

Showing the first eight; more decompositions exist.
