Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 75078, here are decompositions:

37 + 75041 = 75078
41 + 75037 = 75078
61 + 75017 = 75078
67 + 75011 = 75078
137 + 74941 = 75078
149 + 74929 = 75078
181 + 74897 = 75078
191 + 74887 = 75078

Showing the first eight; more decompositions exist.
