Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33619780, here are decompositions:

17 + 33619763 = 33619780
23 + 33619757 = 33619780
41 + 33619739 = 33619780
107 + 33619673 = 33619780
113 + 33619667 = 33619780
191 + 33619589 = 33619780
239 + 33619541 = 33619780
251 + 33619529 = 33619780

Showing the first eight; more decompositions exist.
