Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 45018, here are decompositions:

5 + 45013 = 45018
11 + 45007 = 45018
31 + 44987 = 45018
47 + 44971 = 45018
59 + 44959 = 45018
79 + 44939 = 45018
101 + 44917 = 45018
109 + 44909 = 45018

Showing the first eight; more decompositions exist.
