Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8731628, here are decompositions:

19 + 8731609 = 8731628
97 + 8731531 = 8731628
127 + 8731501 = 8731628
151 + 8731477 = 8731628
181 + 8731447 = 8731628
211 + 8731417 = 8731628
307 + 8731321 = 8731628
379 + 8731249 = 8731628

Showing the first eight; more decompositions exist.
