Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 75148, here are decompositions:

107 + 75041 = 75148
131 + 75017 = 75148
137 + 75011 = 75148
251 + 74897 = 75148
257 + 74891 = 75148
317 + 74831 = 75148
389 + 74759 = 75148
401 + 74747 = 75148

Showing the first eight; more decompositions exist.
