Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8620200, here are decompositions:

11 + 8620189 = 8620200
13 + 8620187 = 8620200
41 + 8620159 = 8620200
59 + 8620141 = 8620200
67 + 8620133 = 8620200
79 + 8620121 = 8620200
89 + 8620111 = 8620200
131 + 8620069 = 8620200

Showing the first eight; more decompositions exist.
