Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8636832, here are decompositions:

13 + 8636819 = 8636832
31 + 8636801 = 8636832
41 + 8636791 = 8636832
53 + 8636779 = 8636832
73 + 8636759 = 8636832
131 + 8636701 = 8636832
199 + 8636633 = 8636832
229 + 8636603 = 8636832

Showing the first eight; more decompositions exist.
