Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 478686, here are decompositions:

7 + 478679 = 478686
59 + 478627 = 478686
83 + 478603 = 478686
97 + 478589 = 478686
107 + 478579 = 478686
113 + 478573 = 478686
163 + 478523 = 478686
193 + 478493 = 478686

Showing the first eight; more decompositions exist.
