Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8720224, here are decompositions:

47 + 8720177 = 8720224
53 + 8720171 = 8720224
113 + 8720111 = 8720224
137 + 8720087 = 8720224
167 + 8720057 = 8720224
197 + 8720027 = 8720224
263 + 8719961 = 8720224
281 + 8719943 = 8720224

Showing the first eight; more decompositions exist.
