Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8732838, here are decompositions:

5 + 8732833 = 8732838
7 + 8732831 = 8732838
19 + 8732819 = 8732838
31 + 8732807 = 8732838
41 + 8732797 = 8732838
89 + 8732749 = 8732838
151 + 8732687 = 8732838
197 + 8732641 = 8732838

Showing the first eight; more decompositions exist.
