Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8725984, here are decompositions:

5 + 8725979 = 8725984
23 + 8725961 = 8725984
53 + 8725931 = 8725984
107 + 8725877 = 8725984
167 + 8725817 = 8725984
227 + 8725757 = 8725984
251 + 8725733 = 8725984
353 + 8725631 = 8725984

Showing the first eight; more decompositions exist.
