Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 75150, here are decompositions:

17 + 75133 = 75150
41 + 75109 = 75150
67 + 75083 = 75150
71 + 75079 = 75150
109 + 75041 = 75150
113 + 75037 = 75150
137 + 75013 = 75150
139 + 75011 = 75150

Showing the first eight; more decompositions exist.
