Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 478566, here are decompositions:

43 + 478523 = 478566
73 + 478493 = 478566
83 + 478483 = 478566
107 + 478459 = 478566
113 + 478453 = 478566
139 + 478427 = 478566
149 + 478417 = 478566
163 + 478403 = 478566

Showing the first eight; more decompositions exist.
