Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8715042, here are decompositions:

13 + 8715029 = 8715042
19 + 8715023 = 8715042
23 + 8715019 = 8715042
29 + 8715013 = 8715042
31 + 8715011 = 8715042
53 + 8714989 = 8715042
59 + 8714983 = 8715042
79 + 8714963 = 8715042

Showing the first eight; more decompositions exist.
