Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33538972, here are decompositions:

23 + 33538949 = 33538972
53 + 33538919 = 33538972
59 + 33538913 = 33538972
113 + 33538859 = 33538972
149 + 33538823 = 33538972
251 + 33538721 = 33538972
263 + 33538709 = 33538972
293 + 33538679 = 33538972

Showing the first eight; more decompositions exist.
