Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8636480, here are decompositions:

7 + 8636473 = 8636480
31 + 8636449 = 8636480
103 + 8636377 = 8636480
211 + 8636269 = 8636480
241 + 8636239 = 8636480
313 + 8636167 = 8636480
373 + 8636107 = 8636480
397 + 8636083 = 8636480

Showing the first eight; more decompositions exist.
