Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8636406, here are decompositions:

17 + 8636389 = 8636406
19 + 8636387 = 8636406
29 + 8636377 = 8636406
59 + 8636347 = 8636406
137 + 8636269 = 8636406
167 + 8636239 = 8636406
239 + 8636167 = 8636406
269 + 8636137 = 8636406

Showing the first eight; more decompositions exist.
