Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8724574, here are decompositions:

107 + 8724467 = 8724574
113 + 8724461 = 8724574
137 + 8724437 = 8724574
197 + 8724377 = 8724574
227 + 8724347 = 8724574
251 + 8724323 = 8724574
263 + 8724311 = 8724574
281 + 8724293 = 8724574

Showing the first eight; more decompositions exist.
