Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33573990, here are decompositions:

13 + 33573977 = 33573990
19 + 33573971 = 33573990
31 + 33573959 = 33573990
41 + 33573949 = 33573990
83 + 33573907 = 33573990
101 + 33573889 = 33573990
113 + 33573877 = 33573990
157 + 33573833 = 33573990

Showing the first eight; more decompositions exist.
