Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8637690, here are decompositions:

23 + 8637667 = 8637690
53 + 8637637 = 8637690
71 + 8637619 = 8637690
73 + 8637617 = 8637690
79 + 8637611 = 8637690
163 + 8637527 = 8637690
167 + 8637523 = 8637690
181 + 8637509 = 8637690

Showing the first eight; more decompositions exist.
