Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33613720, here are decompositions:

59 + 33613661 = 33613720
83 + 33613637 = 33613720
149 + 33613571 = 33613720
227 + 33613493 = 33613720
251 + 33613469 = 33613720
263 + 33613457 = 33613720
281 + 33613439 = 33613720
353 + 33613367 = 33613720

Showing the first eight; more decompositions exist.
