Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8636408, here are decompositions:

19 + 8636389 = 8636408
31 + 8636377 = 8636408
61 + 8636347 = 8636408
139 + 8636269 = 8636408
241 + 8636167 = 8636408
271 + 8636137 = 8636408
409 + 8635999 = 8636408
439 + 8635969 = 8636408

Showing the first eight; more decompositions exist.
