Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33556420, here are decompositions:

17 + 33556403 = 33556420
59 + 33556361 = 33556420
263 + 33556157 = 33556420
383 + 33556037 = 33556420
431 + 33555989 = 33556420
449 + 33555971 = 33556420
461 + 33555959 = 33556420
683 + 33555737 = 33556420

Showing the first eight; more decompositions exist.
