Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 525558, here are decompositions:

17 + 525541 = 525558
29 + 525529 = 525558
41 + 525517 = 525558
67 + 525491 = 525558
97 + 525461 = 525558
101 + 525457 = 525558
127 + 525431 = 525558
149 + 525409 = 525558

Showing the first eight; more decompositions exist.
