Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 38180, here are decompositions:

3 + 38177 = 38180
13 + 38167 = 38180
31 + 38149 = 38180
61 + 38119 = 38180
67 + 38113 = 38180
97 + 38083 = 38180
127 + 38053 = 38180
193 + 37987 = 38180

Showing the first eight; more decompositions exist.
