Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33487472, here are decompositions:

79 + 33487393 = 33487472
163 + 33487309 = 33487472
199 + 33487273 = 33487472
211 + 33487261 = 33487472
283 + 33487189 = 33487472
439 + 33487033 = 33487472
631 + 33486841 = 33487472
643 + 33486829 = 33487472

Showing the first eight; more decompositions exist.
