Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 75220, here are decompositions:

3 + 75217 = 75220
11 + 75209 = 75220
53 + 75167 = 75220
59 + 75161 = 75220
71 + 75149 = 75220
137 + 75083 = 75220
179 + 75041 = 75220
191 + 75029 = 75220

Showing the first eight; more decompositions exist.
