Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 42182, here are decompositions:

3 + 42179 = 42182
13 + 42169 = 42182
43 + 42139 = 42182
109 + 42073 = 42182
139 + 42043 = 42182
163 + 42019 = 42182
199 + 41983 = 42182
223 + 41959 = 42182

Showing the first eight; more decompositions exist.
