Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8720952, here are decompositions:

5 + 8720947 = 8720952
11 + 8720941 = 8720952
41 + 8720911 = 8720952
61 + 8720891 = 8720952
113 + 8720839 = 8720952
179 + 8720773 = 8720952
181 + 8720771 = 8720952
223 + 8720729 = 8720952

Showing the first eight; more decompositions exist.
