Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 101142, here are decompositions:

23 + 101119 = 101142
29 + 101113 = 101142
31 + 101111 = 101142
53 + 101089 = 101142
61 + 101081 = 101142
79 + 101063 = 101142
199 + 100943 = 101142
211 + 100931 = 101142

Showing the first eight; more decompositions exist.
