Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8680558, here are decompositions:

149 + 8680409 = 8680558
167 + 8680391 = 8680558
179 + 8680379 = 8680558
251 + 8680307 = 8680558
281 + 8680277 = 8680558
401 + 8680157 = 8680558
521 + 8680037 = 8680558
587 + 8679971 = 8680558

Showing the first eight; more decompositions exist.
