Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8654458, here are decompositions:

5 + 8654453 = 8654458
11 + 8654447 = 8654458
101 + 8654357 = 8654458
107 + 8654351 = 8654458
227 + 8654231 = 8654458
257 + 8654201 = 8654458
311 + 8654147 = 8654458
347 + 8654111 = 8654458

Showing the first eight; more decompositions exist.
