Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8736868, here are decompositions:

59 + 8736809 = 8736868
149 + 8736719 = 8736868
167 + 8736701 = 8736868
251 + 8736617 = 8736868
359 + 8736509 = 8736868
419 + 8736449 = 8736868
467 + 8736401 = 8736868
659 + 8736209 = 8736868

Showing the first eight; more decompositions exist.
