Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33556560, here are decompositions:

13 + 33556547 = 33556560
29 + 33556531 = 33556560
31 + 33556529 = 33556560
53 + 33556507 = 33556560
61 + 33556499 = 33556560
67 + 33556493 = 33556560
101 + 33556459 = 33556560
131 + 33556429 = 33556560

Showing the first eight; more decompositions exist.
