Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33603990, here are decompositions:

19 + 33603971 = 33603990
41 + 33603949 = 33603990
61 + 33603929 = 33603990
67 + 33603923 = 33603990
89 + 33603901 = 33603990
97 + 33603893 = 33603990
131 + 33603859 = 33603990
151 + 33603839 = 33603990

Showing the first eight; more decompositions exist.
