Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8627728, here are decompositions:

29 + 8627699 = 8627728
47 + 8627681 = 8627728
89 + 8627639 = 8627728
101 + 8627627 = 8627728
167 + 8627561 = 8627728
281 + 8627447 = 8627728
311 + 8627417 = 8627728
587 + 8627141 = 8627728

Showing the first eight; more decompositions exist.
