Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 86168, here are decompositions:

7 + 86161 = 86168
31 + 86137 = 86168
37 + 86131 = 86168
139 + 86029 = 86168
151 + 86017 = 86168
157 + 86011 = 86168
331 + 85837 = 86168
337 + 85831 = 86168

Showing the first eight; more decompositions exist.
