Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 39572, here are decompositions:

3 + 39569 = 39572
31 + 39541 = 39572
61 + 39511 = 39572
73 + 39499 = 39572
163 + 39409 = 39572
199 + 39373 = 39572
229 + 39343 = 39572
271 + 39301 = 39572

Showing the first eight; more decompositions exist.
