Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8627828, here are decompositions:

19 + 8627809 = 8627828
127 + 8627701 = 8627828
211 + 8627617 = 8627828
331 + 8627497 = 8627828
397 + 8627431 = 8627828
457 + 8627371 = 8627828
487 + 8627341 = 8627828
499 + 8627329 = 8627828

Showing the first eight; more decompositions exist.
