Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8720200, here are decompositions:

11 + 8720189 = 8720200
23 + 8720177 = 8720200
29 + 8720171 = 8720200
89 + 8720111 = 8720200
113 + 8720087 = 8720200
173 + 8720027 = 8720200
239 + 8719961 = 8720200
257 + 8719943 = 8720200

Showing the first eight; more decompositions exist.
