Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 525522, here are decompositions:

5 + 525517 = 525522
29 + 525493 = 525522
31 + 525491 = 525522
61 + 525461 = 525522
83 + 525439 = 525522
89 + 525433 = 525522
113 + 525409 = 525522
131 + 525391 = 525522

Showing the first eight; more decompositions exist.
