Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 5142, here are decompositions:

23 + 5119 = 5142
29 + 5113 = 5142
41 + 5101 = 5142
43 + 5099 = 5142
61 + 5081 = 5142
83 + 5059 = 5142
103 + 5039 = 5142
131 + 5011 = 5142

Showing the first eight; more decompositions exist.
