Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33556642, here are decompositions:

29 + 33556613 = 33556642
71 + 33556571 = 33556642
83 + 33556559 = 33556642
113 + 33556529 = 33556642
149 + 33556493 = 33556642
239 + 33556403 = 33556642
281 + 33556361 = 33556642
653 + 33555989 = 33556642

Showing the first eight; more decompositions exist.
