Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 75018, here are decompositions:

5 + 75013 = 75018
7 + 75011 = 75018
59 + 74959 = 75018
89 + 74929 = 75018
127 + 74891 = 75018
131 + 74887 = 75018
149 + 74869 = 75018
157 + 74861 = 75018

Showing the first eight; more decompositions exist.
