Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 38972, here are decompositions:

13 + 38959 = 38972
19 + 38953 = 38972
139 + 38833 = 38972
151 + 38821 = 38972
181 + 38791 = 38972
223 + 38749 = 38972
379 + 38593 = 38972
523 + 38449 = 38972

Showing the first eight; more decompositions exist.
