Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8636894, here are decompositions:

37 + 8636857 = 8636894
103 + 8636791 = 8636894
157 + 8636737 = 8636894
181 + 8636713 = 8636894
193 + 8636701 = 8636894
223 + 8636671 = 8636894
307 + 8636587 = 8636894
313 + 8636581 = 8636894

Showing the first eight; more decompositions exist.
