Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 45640, here are decompositions:

41 + 45599 = 45640
53 + 45587 = 45640
71 + 45569 = 45640
83 + 45557 = 45640
107 + 45533 = 45640
137 + 45503 = 45640
149 + 45491 = 45640
227 + 45413 = 45640

Showing the first eight; more decompositions exist.
