Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 525678, here are decompositions:

7 + 525671 = 525678
29 + 525649 = 525678
37 + 525641 = 525678
71 + 525607 = 525678
79 + 525599 = 525678
107 + 525571 = 525678
137 + 525541 = 525678
149 + 525529 = 525678

Showing the first eight; more decompositions exist.
