Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8636390, here are decompositions:

3 + 8636387 = 8636390
13 + 8636377 = 8636390
43 + 8636347 = 8636390
127 + 8636263 = 8636390
151 + 8636239 = 8636390
223 + 8636167 = 8636390
283 + 8636107 = 8636390
307 + 8636083 = 8636390

Showing the first eight; more decompositions exist.
