Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33555890, here are decompositions:

7 + 33555883 = 33555890
31 + 33555859 = 33555890
37 + 33555853 = 33555890
73 + 33555817 = 33555890
139 + 33555751 = 33555890
163 + 33555727 = 33555890
211 + 33555679 = 33555890
223 + 33555667 = 33555890

Showing the first eight; more decompositions exist.
