Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1042130, here are decompositions:

7 + 1042123 = 1042130
31 + 1042099 = 1042130
43 + 1042087 = 1042130
109 + 1042021 = 1042130
139 + 1041991 = 1042130
181 + 1041949 = 1042130
211 + 1041919 = 1042130
223 + 1041907 = 1042130

Showing the first eight; more decompositions exist.
