Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8749998, here are decompositions:

7 + 8749991 = 8749998
17 + 8749981 = 8749998
71 + 8749927 = 8749998
107 + 8749891 = 8749998
151 + 8749847 = 8749998
157 + 8749841 = 8749998
181 + 8749817 = 8749998
211 + 8749787 = 8749998

Showing the first eight; more decompositions exist.
