Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8637130, here are decompositions:

11 + 8637119 = 8637130
23 + 8637107 = 8637130
71 + 8637059 = 8637130
113 + 8637017 = 8637130
311 + 8636819 = 8637130
389 + 8636741 = 8637130
503 + 8636627 = 8637130
587 + 8636543 = 8637130

Showing the first eight; more decompositions exist.
