Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8637540, here are decompositions:

13 + 8637527 = 8637540
17 + 8637523 = 8637540
19 + 8637521 = 8637540
31 + 8637509 = 8637540
47 + 8637493 = 8637540
59 + 8637481 = 8637540
73 + 8637467 = 8637540
89 + 8637451 = 8637540

Showing the first eight; more decompositions exist.
