Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8736988, here are decompositions:

89 + 8736899 = 8736988
107 + 8736881 = 8736988
179 + 8736809 = 8736988
269 + 8736719 = 8736988
479 + 8736509 = 8736988
587 + 8736401 = 8736988
647 + 8736341 = 8736988
797 + 8736191 = 8736988

Showing the first eight; more decompositions exist.
