Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 525648, here are decompositions:

7 + 525641 = 525648
41 + 525607 = 525648
107 + 525541 = 525648
131 + 525517 = 525648
157 + 525491 = 525648
181 + 525467 = 525648
191 + 525457 = 525648
239 + 525409 = 525648

Showing the first eight; more decompositions exist.
