Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 86142, here are decompositions:

5 + 86137 = 86142
11 + 86131 = 86142
29 + 86113 = 86142
31 + 86111 = 86142
59 + 86083 = 86142
73 + 86069 = 86142
113 + 86029 = 86142
131 + 86011 = 86142

Showing the first eight; more decompositions exist.
