Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8720998, here are decompositions:

29 + 8720969 = 8720998
107 + 8720891 = 8720998
179 + 8720819 = 8720998
191 + 8720807 = 8720998
227 + 8720771 = 8720998
269 + 8720729 = 8720998
311 + 8720687 = 8720998
317 + 8720681 = 8720998

Showing the first eight; more decompositions exist.
