Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8625998, here are decompositions:

19 + 8625979 = 8625998
37 + 8625961 = 8625998
97 + 8625901 = 8625998
109 + 8625889 = 8625998
211 + 8625787 = 8625998
349 + 8625649 = 8625998
439 + 8625559 = 8625998
457 + 8625541 = 8625998

Showing the first eight; more decompositions exist.
