Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 74280, here are decompositions:

23 + 74257 = 74280
61 + 74219 = 74280
71 + 74209 = 74280
79 + 74201 = 74280
83 + 74197 = 74280
103 + 74177 = 74280
113 + 74167 = 74280
131 + 74149 = 74280

Showing the first eight; more decompositions exist.
