Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8715028, here are decompositions:

5 + 8715023 = 8715028
17 + 8715011 = 8715028
71 + 8714957 = 8715028
107 + 8714921 = 8715028
239 + 8714789 = 8715028
359 + 8714669 = 8715028
389 + 8714639 = 8715028
419 + 8714609 = 8715028

Showing the first eight; more decompositions exist.
