Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8625988, here are decompositions:

5 + 8625983 = 8625988
29 + 8625959 = 8625988
167 + 8625821 = 8625988
179 + 8625809 = 8625988
281 + 8625707 = 8625988
347 + 8625641 = 8625988
389 + 8625599 = 8625988
401 + 8625587 = 8625988

Showing the first eight; more decompositions exist.
