Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8642888, here are decompositions:

31 + 8642857 = 8642888
127 + 8642761 = 8642888
307 + 8642581 = 8642888
379 + 8642509 = 8642888
421 + 8642467 = 8642888
439 + 8642449 = 8642888
607 + 8642281 = 8642888
691 + 8642197 = 8642888

Showing the first eight; more decompositions exist.
