Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 71142, here are decompositions:

13 + 71129 = 71142
23 + 71119 = 71142
53 + 71089 = 71142
61 + 71081 = 71142
73 + 71069 = 71142
83 + 71059 = 71142
103 + 71039 = 71142
131 + 71011 = 71142

Showing the first eight; more decompositions exist.
