Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33556890, here are decompositions:

11 + 33556879 = 33556890
13 + 33556877 = 33556890
23 + 33556867 = 33556890
43 + 33556847 = 33556890
53 + 33556837 = 33556890
67 + 33556823 = 33556890
79 + 33556811 = 33556890
167 + 33556723 = 33556890

Showing the first eight; more decompositions exist.
