Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8715072, here are decompositions:

13 + 8715059 = 8715072
31 + 8715041 = 8715072
43 + 8715029 = 8715072
53 + 8715019 = 8715072
59 + 8715013 = 8715072
61 + 8715011 = 8715072
83 + 8714989 = 8715072
89 + 8714983 = 8715072

Showing the first eight; more decompositions exist.
