Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8637538, here are decompositions:

11 + 8637527 = 8637538
17 + 8637521 = 8637538
29 + 8637509 = 8637538
47 + 8637491 = 8637538
71 + 8637467 = 8637538
89 + 8637449 = 8637538
197 + 8637341 = 8637538
227 + 8637311 = 8637538

Showing the first eight; more decompositions exist.
