Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8732820, here are decompositions:

13 + 8732807 = 8732820
23 + 8732797 = 8732820
71 + 8732749 = 8732820
101 + 8732719 = 8732820
167 + 8732653 = 8732820
179 + 8732641 = 8732820
181 + 8732639 = 8732820
193 + 8732627 = 8732820

Showing the first eight; more decompositions exist.
