Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8680480, here are decompositions:

41 + 8680439 = 8680480
71 + 8680409 = 8680480
89 + 8680391 = 8680480
101 + 8680379 = 8680480
167 + 8680313 = 8680480
173 + 8680307 = 8680480
251 + 8680229 = 8680480
293 + 8680187 = 8680480

Showing the first eight; more decompositions exist.
