Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8715090, here are decompositions:

11 + 8715079 = 8715090
31 + 8715059 = 8715090
61 + 8715029 = 8715090
67 + 8715023 = 8715090
71 + 8715019 = 8715090
79 + 8715011 = 8715090
101 + 8714989 = 8715090
107 + 8714983 = 8715090

Showing the first eight; more decompositions exist.
