Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8673628, here are decompositions:

17 + 8673611 = 8673628
59 + 8673569 = 8673628
239 + 8673389 = 8673628
251 + 8673377 = 8673628
269 + 8673359 = 8673628
281 + 8673347 = 8673628
419 + 8673209 = 8673628
461 + 8673167 = 8673628

Showing the first eight; more decompositions exist.
