Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8720286, here are decompositions:

5 + 8720281 = 8720286
53 + 8720233 = 8720286
59 + 8720227 = 8720286
97 + 8720189 = 8720286
109 + 8720177 = 8720286
149 + 8720137 = 8720286
167 + 8720119 = 8720286
173 + 8720113 = 8720286

Showing the first eight; more decompositions exist.
