Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1042172, here are decompositions:

31 + 1042141 = 1042172
73 + 1042099 = 1042172
151 + 1042021 = 1042172
181 + 1041991 = 1042172
211 + 1041961 = 1042172
223 + 1041949 = 1042172
283 + 1041889 = 1042172
331 + 1041841 = 1042172

Showing the first eight; more decompositions exist.
