Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8637772, here are decompositions:

23 + 8637749 = 8637772
71 + 8637701 = 8637772
131 + 8637641 = 8637772
251 + 8637521 = 8637772
263 + 8637509 = 8637772
281 + 8637491 = 8637772
431 + 8637341 = 8637772
449 + 8637323 = 8637772

Showing the first eight; more decompositions exist.
