Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33511816, here are decompositions:

47 + 33511769 = 33511816
59 + 33511757 = 33511816
89 + 33511727 = 33511816
137 + 33511679 = 33511816
269 + 33511547 = 33511816
419 + 33511397 = 33511816
449 + 33511367 = 33511816
479 + 33511337 = 33511816

Showing the first eight; more decompositions exist.
