Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8625994, here are decompositions:

11 + 8625983 = 8625994
173 + 8625821 = 8625994
353 + 8625641 = 8625994
467 + 8625527 = 8625994
563 + 8625431 = 8625994
677 + 8625317 = 8625994
683 + 8625311 = 8625994
761 + 8625233 = 8625994

Showing the first eight; more decompositions exist.
