Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 86174, here are decompositions:

3 + 86171 = 86174
13 + 86161 = 86174
31 + 86143 = 86174
37 + 86137 = 86174
43 + 86131 = 86174
61 + 86113 = 86174
97 + 86077 = 86174
157 + 86017 = 86174

Showing the first eight; more decompositions exist.
