Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 75172, here are decompositions:

3 + 75169 = 75172
5 + 75167 = 75172
11 + 75161 = 75172
23 + 75149 = 75172
89 + 75083 = 75172
131 + 75041 = 75172
239 + 74933 = 75172
269 + 74903 = 75172

Showing the first eight; more decompositions exist.
