Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33531472, here are decompositions:

3 + 33531469 = 33531472
5 + 33531467 = 33531472
41 + 33531431 = 33531472
59 + 33531413 = 33531472
83 + 33531389 = 33531472
173 + 33531299 = 33531472
239 + 33531233 = 33531472
389 + 33531083 = 33531472

Showing the first eight; more decompositions exist.
