Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33583890, here are decompositions:

13 + 33583877 = 33583890
17 + 33583873 = 33583890
31 + 33583859 = 33583890
103 + 33583787 = 33583890
113 + 33583777 = 33583890
127 + 33583763 = 33583890
163 + 33583727 = 33583890
173 + 33583717 = 33583890

Showing the first eight; more decompositions exist.
