Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8732686, here are decompositions:

47 + 8732639 = 8732686
59 + 8732627 = 8732686
113 + 8732573 = 8732686
197 + 8732489 = 8732686
239 + 8732447 = 8732686
257 + 8732429 = 8732686
269 + 8732417 = 8732686
317 + 8732369 = 8732686

Showing the first eight; more decompositions exist.
