Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8638396, here are decompositions:

17 + 8638379 = 8638396
23 + 8638373 = 8638396
47 + 8638349 = 8638396
59 + 8638337 = 8638396
113 + 8638283 = 8638396
149 + 8638247 = 8638396
167 + 8638229 = 8638396
197 + 8638199 = 8638396

Showing the first eight; more decompositions exist.
