Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 174280, here are decompositions:

17 + 174263 = 174280
23 + 174257 = 174280
59 + 174221 = 174280
83 + 174197 = 174280
131 + 174149 = 174280
137 + 174143 = 174280
179 + 174101 = 174280
233 + 174047 = 174280

Showing the first eight; more decompositions exist.
