Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8670988, here are decompositions:

41 + 8670947 = 8670988
47 + 8670941 = 8670988
101 + 8670887 = 8670988
197 + 8670791 = 8670988
479 + 8670509 = 8670988
617 + 8670371 = 8670988
797 + 8670191 = 8670988
881 + 8670107 = 8670988

Showing the first eight; more decompositions exist.
