Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33553890, here are decompositions:

11 + 33553879 = 33553890
53 + 33553837 = 33553890
103 + 33553787 = 33553890
131 + 33553759 = 33553890
151 + 33553739 = 33553890
163 + 33553727 = 33553890
193 + 33553697 = 33553890
197 + 33553693 = 33553890

Showing the first eight; more decompositions exist.
