Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 943142, here are decompositions:

3 + 943139 = 943142
61 + 943081 = 943142
139 + 943003 = 943142
163 + 942979 = 943142
199 + 942943 = 943142
241 + 942901 = 943142
283 + 942859 = 943142
331 + 942811 = 943142

Showing the first eight; more decompositions exist.
