Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33543642, here are decompositions:

59 + 33543583 = 33543642
89 + 33543553 = 33543642
103 + 33543539 = 33543642
113 + 33543529 = 33543642
131 + 33543511 = 33543642
269 + 33543373 = 33543642
283 + 33543359 = 33543642
311 + 33543331 = 33543642

Showing the first eight; more decompositions exist.
