Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8717072, here are decompositions:

31 + 8717041 = 8717072
61 + 8717011 = 8717072
73 + 8716999 = 8717072
181 + 8716891 = 8717072
211 + 8716861 = 8717072
229 + 8716843 = 8717072
313 + 8716759 = 8717072
379 + 8716693 = 8717072

Showing the first eight; more decompositions exist.
