Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 83180, here are decompositions:

3 + 83177 = 83180
43 + 83137 = 83180
79 + 83101 = 83180
103 + 83077 = 83180
109 + 83071 = 83180
157 + 83023 = 83180
199 + 82981 = 83180
241 + 82939 = 83180

Showing the first eight; more decompositions exist.
