Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 45120, here are decompositions:

37 + 45083 = 45120
43 + 45077 = 45120
59 + 45061 = 45120
67 + 45053 = 45120
107 + 45013 = 45120
113 + 45007 = 45120
137 + 44983 = 45120
149 + 44971 = 45120

Showing the first eight; more decompositions exist.
