Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 39290, here are decompositions:

61 + 39229 = 39290
73 + 39217 = 39290
109 + 39181 = 39290
127 + 39163 = 39290
151 + 39139 = 39290
157 + 39133 = 39290
193 + 39097 = 39290
211 + 39079 = 39290

Showing the first eight; more decompositions exist.
