Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8680540, here are decompositions:

59 + 8680481 = 8680540
101 + 8680439 = 8680540
131 + 8680409 = 8680540
149 + 8680391 = 8680540
227 + 8680313 = 8680540
233 + 8680307 = 8680540
263 + 8680277 = 8680540
311 + 8680229 = 8680540

Showing the first eight; more decompositions exist.
