Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8732638, here are decompositions:

11 + 8732627 = 8732638
137 + 8732501 = 8732638
149 + 8732489 = 8732638
191 + 8732447 = 8732638
227 + 8732411 = 8732638
269 + 8732369 = 8732638
347 + 8732291 = 8732638
449 + 8732189 = 8732638

Showing the first eight; more decompositions exist.
