Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8623788, here are decompositions:

31 + 8623757 = 8623788
37 + 8623751 = 8623788
59 + 8623729 = 8623788
67 + 8623721 = 8623788
71 + 8623717 = 8623788
101 + 8623687 = 8623788
109 + 8623679 = 8623788
127 + 8623661 = 8623788

Showing the first eight; more decompositions exist.
