Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 75138, here are decompositions:

5 + 75133 = 75138
29 + 75109 = 75138
59 + 75079 = 75138
97 + 75041 = 75138
101 + 75037 = 75138
109 + 75029 = 75138
127 + 75011 = 75138
179 + 74959 = 75138

Showing the first eight; more decompositions exist.
