Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8636242, here are decompositions:

3 + 8636239 = 8636242
5 + 8636237 = 8636242
23 + 8636219 = 8636242
101 + 8636141 = 8636242
113 + 8636129 = 8636242
149 + 8636093 = 8636242
359 + 8635883 = 8636242
389 + 8635853 = 8636242

Showing the first eight; more decompositions exist.
