Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8637760, here are decompositions:

11 + 8637749 = 8637760
59 + 8637701 = 8637760
149 + 8637611 = 8637760
233 + 8637527 = 8637760
239 + 8637521 = 8637760
251 + 8637509 = 8637760
269 + 8637491 = 8637760
293 + 8637467 = 8637760

Showing the first eight; more decompositions exist.
