Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8637802, here are decompositions:

11 + 8637791 = 8637802
23 + 8637779 = 8637802
53 + 8637749 = 8637802
101 + 8637701 = 8637802
191 + 8637611 = 8637802
281 + 8637521 = 8637802
293 + 8637509 = 8637802
311 + 8637491 = 8637802

Showing the first eight; more decompositions exist.
