Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8725998, here are decompositions:

7 + 8725991 = 8725998
11 + 8725987 = 8725998
19 + 8725979 = 8725998
37 + 8725961 = 8725998
67 + 8725931 = 8725998
157 + 8725841 = 8725998
167 + 8725831 = 8725998
181 + 8725817 = 8725998

Showing the first eight; more decompositions exist.
