Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 113142, here are decompositions:

11 + 113131 = 113142
19 + 113123 = 113142
31 + 113111 = 113142
53 + 113089 = 113142
59 + 113083 = 113142
61 + 113081 = 113142
79 + 113063 = 113142
101 + 113041 = 113142

Showing the first eight; more decompositions exist.
