Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8182, here are decompositions:

3 + 8179 = 8182
11 + 8171 = 8182
59 + 8123 = 8182
71 + 8111 = 8182
89 + 8093 = 8182
101 + 8081 = 8182
113 + 8069 = 8182
173 + 8009 = 8182

Showing the first eight; more decompositions exist.
