Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 478558, here are decompositions:

107 + 478451 = 478558
131 + 478427 = 478558
137 + 478421 = 478558
167 + 478391 = 478558
317 + 478241 = 478558
359 + 478199 = 478558
389 + 478169 = 478558
401 + 478157 = 478558

Showing the first eight; more decompositions exist.
