Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33619728, here are decompositions:

41 + 33619687 = 33619728
47 + 33619681 = 33619728
59 + 33619669 = 33619728
61 + 33619667 = 33619728
101 + 33619627 = 33619728
139 + 33619589 = 33619728
151 + 33619577 = 33619728
167 + 33619561 = 33619728

Showing the first eight; more decompositions exist.
