Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 525426, here are decompositions:

17 + 525409 = 525426
29 + 525397 = 525426
47 + 525379 = 525426
53 + 525373 = 525426
67 + 525359 = 525426
73 + 525353 = 525426
113 + 525313 = 525426
127 + 525299 = 525426

Showing the first eight; more decompositions exist.
