Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8680360, here are decompositions:

23 + 8680337 = 8680360
47 + 8680313 = 8680360
53 + 8680307 = 8680360
83 + 8680277 = 8680360
131 + 8680229 = 8680360
173 + 8680187 = 8680360
239 + 8680121 = 8680360
257 + 8680103 = 8680360

Showing the first eight; more decompositions exist.
