Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 45072, here are decompositions:

11 + 45061 = 45072
19 + 45053 = 45072
59 + 45013 = 45072
89 + 44983 = 45072
101 + 44971 = 45072
109 + 44963 = 45072
113 + 44959 = 45072
163 + 44909 = 45072

Showing the first eight; more decompositions exist.
