Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8726224, here are decompositions:

83 + 8726141 = 8726224
131 + 8726093 = 8726224
137 + 8726087 = 8726224
173 + 8726051 = 8726224
197 + 8726027 = 8726224
233 + 8725991 = 8726224
263 + 8725961 = 8726224
293 + 8725931 = 8726224

Showing the first eight; more decompositions exist.
