Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8720848, here are decompositions:

11 + 8720837 = 8720848
29 + 8720819 = 8720848
41 + 8720807 = 8720848
167 + 8720681 = 8720848
251 + 8720597 = 8720848
317 + 8720531 = 8720848
359 + 8720489 = 8720848
401 + 8720447 = 8720848

Showing the first eight; more decompositions exist.
