Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 75280, here are decompositions:

3 + 75277 = 75280
11 + 75269 = 75280
41 + 75239 = 75280
53 + 75227 = 75280
71 + 75209 = 75280
113 + 75167 = 75280
131 + 75149 = 75280
197 + 75083 = 75280

Showing the first eight; more decompositions exist.
