Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8729022, here are decompositions:

53 + 8728969 = 8729022
59 + 8728963 = 8729022
79 + 8728943 = 8729022
101 + 8728921 = 8729022
139 + 8728883 = 8729022
173 + 8728849 = 8729022
199 + 8728823 = 8729022
311 + 8728711 = 8729022

Showing the first eight; more decompositions exist.
