Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8637766, here are decompositions:

17 + 8637749 = 8637766
149 + 8637617 = 8637766
239 + 8637527 = 8637766
257 + 8637509 = 8637766
317 + 8637449 = 8637766
443 + 8637323 = 8637766
503 + 8637263 = 8637766
509 + 8637257 = 8637766

Showing the first eight; more decompositions exist.
