Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8715780, here are decompositions:

11 + 8715769 = 8715780
19 + 8715761 = 8715780
61 + 8715719 = 8715780
71 + 8715709 = 8715780
83 + 8715697 = 8715780
107 + 8715673 = 8715780
109 + 8715671 = 8715780
113 + 8715667 = 8715780

Showing the first eight; more decompositions exist.
