Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8738668, here are decompositions:

89 + 8738579 = 8738668
101 + 8738567 = 8738668
269 + 8738399 = 8738668
317 + 8738351 = 8738668
467 + 8738201 = 8738668
797 + 8737871 = 8738668
839 + 8737829 = 8738668
971 + 8737697 = 8738668

Showing the first eight; more decompositions exist.
