Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8636448, here are decompositions:

59 + 8636389 = 8636448
61 + 8636387 = 8636448
71 + 8636377 = 8636448
101 + 8636347 = 8636448
179 + 8636269 = 8636448
211 + 8636237 = 8636448
229 + 8636219 = 8636448
281 + 8636167 = 8636448

Showing the first eight; more decompositions exist.
