Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 75040, here are decompositions:

3 + 75037 = 75040
11 + 75029 = 75040
23 + 75017 = 75040
29 + 75011 = 75040
107 + 74933 = 75040
137 + 74903 = 75040
149 + 74891 = 75040
167 + 74873 = 75040

Showing the first eight; more decompositions exist.
