Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33555628, here are decompositions:

11 + 33555617 = 33555628
17 + 33555611 = 33555628
101 + 33555527 = 33555628
131 + 33555497 = 33555628
167 + 33555461 = 33555628
179 + 33555449 = 33555628
251 + 33555377 = 33555628
311 + 33555317 = 33555628

Showing the first eight; more decompositions exist.
