Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 45158, here are decompositions:

19 + 45139 = 45158
31 + 45127 = 45158
37 + 45121 = 45158
97 + 45061 = 45158
151 + 45007 = 45158
199 + 44959 = 45158
241 + 44917 = 45158
271 + 44887 = 45158

Showing the first eight; more decompositions exist.
