Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33513472, here are decompositions:

71 + 33513401 = 33513472
191 + 33513281 = 33513472
269 + 33513203 = 33513472
449 + 33513023 = 33513472
599 + 33512873 = 33513472
719 + 33512753 = 33513472
1031 + 33512441 = 33513472
1061 + 33512411 = 33513472

Showing the first eight; more decompositions exist.
