Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 79142, here are decompositions:

3 + 79139 = 79142
31 + 79111 = 79142
79 + 79063 = 79142
103 + 79039 = 79142
163 + 78979 = 79142
223 + 78919 = 79142
241 + 78901 = 79142
421 + 78721 = 79142

Showing the first eight; more decompositions exist.
