Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33619818, here are decompositions:

7 + 33619811 = 33619818
17 + 33619801 = 33619818
19 + 33619799 = 33619818
47 + 33619771 = 33619818
61 + 33619757 = 33619818
79 + 33619739 = 33619818
131 + 33619687 = 33619818
137 + 33619681 = 33619818

Showing the first eight; more decompositions exist.
