Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 525548, here are decompositions:

7 + 525541 = 525548
19 + 525529 = 525548
31 + 525517 = 525548
109 + 525439 = 525548
139 + 525409 = 525548
151 + 525397 = 525548
157 + 525391 = 525548
307 + 525241 = 525548

Showing the first eight; more decompositions exist.
