Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 45162, here are decompositions:

23 + 45139 = 45162
31 + 45131 = 45162
41 + 45121 = 45162
43 + 45119 = 45162
79 + 45083 = 45162
101 + 45061 = 45162
109 + 45053 = 45162
149 + 45013 = 45162

Showing the first eight; more decompositions exist.
