Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 523678, here are decompositions:

5 + 523673 = 523678
11 + 523667 = 523678
41 + 523637 = 523678
47 + 523631 = 523678
101 + 523577 = 523678
107 + 523571 = 523678
137 + 523541 = 523678
167 + 523511 = 523678

Showing the first eight; more decompositions exist.
