Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8636472, here are decompositions:

23 + 8636449 = 8636472
83 + 8636389 = 8636472
211 + 8636261 = 8636472
233 + 8636239 = 8636472
331 + 8636141 = 8636472
349 + 8636123 = 8636472
379 + 8636093 = 8636472
389 + 8636083 = 8636472

Showing the first eight; more decompositions exist.
