Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 20142, here are decompositions:

13 + 20129 = 20142
19 + 20123 = 20142
29 + 20113 = 20142
41 + 20101 = 20142
53 + 20089 = 20142
71 + 20071 = 20142
79 + 20063 = 20142
113 + 20029 = 20142

Showing the first eight; more decompositions exist.
