Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8637982, here are decompositions:

29 + 8637953 = 8637982
53 + 8637929 = 8637982
113 + 8637869 = 8637982
191 + 8637791 = 8637982
233 + 8637749 = 8637982
281 + 8637701 = 8637982
461 + 8637521 = 8637982
491 + 8637491 = 8637982

Showing the first eight; more decompositions exist.
