Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33587278, here are decompositions:

17 + 33587261 = 33587278
41 + 33587237 = 33587278
59 + 33587219 = 33587278
167 + 33587111 = 33587278
227 + 33587051 = 33587278
239 + 33587039 = 33587278
281 + 33586997 = 33587278
449 + 33586829 = 33587278

Showing the first eight; more decompositions exist.
