Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33610640, here are decompositions:

13 + 33610627 = 33610640
31 + 33610609 = 33610640
61 + 33610579 = 33610640
109 + 33610531 = 33610640
139 + 33610501 = 33610640
241 + 33610399 = 33610640
277 + 33610363 = 33610640
337 + 33610303 = 33610640

Showing the first eight; more decompositions exist.
