Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33550642, here are decompositions:

11 + 33550631 = 33550642
23 + 33550619 = 33550642
131 + 33550511 = 33550642
311 + 33550331 = 33550642
599 + 33550043 = 33550642
659 + 33549983 = 33550642
743 + 33549899 = 33550642
809 + 33549833 = 33550642

Showing the first eight; more decompositions exist.
