Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8720896, here are decompositions:

5 + 8720891 = 8720896
59 + 8720837 = 8720896
89 + 8720807 = 8720896
113 + 8720783 = 8720896
167 + 8720729 = 8720896
269 + 8720627 = 8720896
383 + 8720513 = 8720896
419 + 8720477 = 8720896

Showing the first eight; more decompositions exist.
