Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8654578, here are decompositions:

5 + 8654573 = 8654578
89 + 8654489 = 8654578
131 + 8654447 = 8654578
197 + 8654381 = 8654578
227 + 8654351 = 8654578
239 + 8654339 = 8654578
347 + 8654231 = 8654578
431 + 8654147 = 8654578

Showing the first eight; more decompositions exist.
