Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8725992, here are decompositions:

5 + 8725987 = 8725992
13 + 8725979 = 8725992
29 + 8725963 = 8725992
31 + 8725961 = 8725992
43 + 8725949 = 8725992
61 + 8725931 = 8725992
151 + 8725841 = 8725992
179 + 8725813 = 8725992

Showing the first eight; more decompositions exist.
