Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 45090, here are decompositions:

7 + 45083 = 45090
13 + 45077 = 45090
29 + 45061 = 45090
37 + 45053 = 45090
83 + 45007 = 45090
103 + 44987 = 45090
107 + 44983 = 45090
127 + 44963 = 45090

Showing the first eight; more decompositions exist.
