Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 45138, here are decompositions:

7 + 45131 = 45138
11 + 45127 = 45138
17 + 45121 = 45138
19 + 45119 = 45138
61 + 45077 = 45138
131 + 45007 = 45138
151 + 44987 = 45138
167 + 44971 = 45138

Showing the first eight; more decompositions exist.
