Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8680438, here are decompositions:

29 + 8680409 = 8680438
47 + 8680391 = 8680438
59 + 8680379 = 8680438
101 + 8680337 = 8680438
131 + 8680307 = 8680438
251 + 8680187 = 8680438
281 + 8680157 = 8680438
317 + 8680121 = 8680438

Showing the first eight; more decompositions exist.
