Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 45036, here are decompositions:

23 + 45013 = 45036
29 + 45007 = 45036
53 + 44983 = 45036
73 + 44963 = 45036
83 + 44953 = 45036
97 + 44939 = 45036
109 + 44927 = 45036
127 + 44909 = 45036

Showing the first eight; more decompositions exist.
