Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8740480, here are decompositions:

53 + 8740427 = 8740480
107 + 8740373 = 8740480
113 + 8740367 = 8740480
149 + 8740331 = 8740480
179 + 8740301 = 8740480
191 + 8740289 = 8740480
293 + 8740187 = 8740480
311 + 8740169 = 8740480

Showing the first eight; more decompositions exist.
