Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 86156, here are decompositions:

13 + 86143 = 86156
19 + 86137 = 86156
43 + 86113 = 86156
73 + 86083 = 86156
79 + 86077 = 86156
127 + 86029 = 86156
139 + 86017 = 86156
157 + 85999 = 86156

Showing the first eight; more decompositions exist.
