Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8638358, here are decompositions:

19 + 8638339 = 8638358
31 + 8638327 = 8638358
67 + 8638291 = 8638358
139 + 8638219 = 8638358
151 + 8638207 = 8638358
241 + 8638117 = 8638358
307 + 8638051 = 8638358
367 + 8637991 = 8638358

Showing the first eight; more decompositions exist.
