Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 525546, here are decompositions:

5 + 525541 = 525546
13 + 525533 = 525546
17 + 525529 = 525546
29 + 525517 = 525546
53 + 525493 = 525546
79 + 525467 = 525546
89 + 525457 = 525546
107 + 525439 = 525546

Showing the first eight; more decompositions exist.
