Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8654428, here are decompositions:

47 + 8654381 = 8654428
71 + 8654357 = 8654428
89 + 8654339 = 8654428
179 + 8654249 = 8654428
191 + 8654237 = 8654428
197 + 8654231 = 8654428
227 + 8654201 = 8654428
257 + 8654171 = 8654428

Showing the first eight; more decompositions exist.
