Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 45020, here are decompositions:

7 + 45013 = 45020
13 + 45007 = 45020
37 + 44983 = 45020
61 + 44959 = 45020
67 + 44953 = 45020
103 + 44917 = 45020
127 + 44893 = 45020
181 + 44839 = 45020

Showing the first eight; more decompositions exist.
