Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8637786, here are decompositions:

7 + 8637779 = 8637786
37 + 8637749 = 8637786
89 + 8637697 = 8637786
149 + 8637637 = 8637786
167 + 8637619 = 8637786
263 + 8637523 = 8637786
277 + 8637509 = 8637786
293 + 8637493 = 8637786

Showing the first eight; more decompositions exist.
