Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 86160, here are decompositions:

17 + 86143 = 86160
23 + 86137 = 86160
29 + 86131 = 86160
43 + 86117 = 86160
47 + 86113 = 86160
83 + 86077 = 86160
131 + 86029 = 86160
149 + 86011 = 86160

Showing the first eight; more decompositions exist.
