Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8732928, here are decompositions:

5 + 8732923 = 8732928
7 + 8732921 = 8732928
41 + 8732887 = 8732928
59 + 8732869 = 8732928
67 + 8732861 = 8732928
89 + 8732839 = 8732928
97 + 8732831 = 8732928
109 + 8732819 = 8732928

Showing the first eight; more decompositions exist.
