Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 182170, here are decompositions:

3 + 182167 = 182170
11 + 182159 = 182170
29 + 182141 = 182170
41 + 182129 = 182170
47 + 182123 = 182170
59 + 182111 = 182170
71 + 182099 = 182170
113 + 182057 = 182170

Showing the first eight; more decompositions exist.
