Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 525864, here are decompositions:

47 + 525817 = 525864
83 + 525781 = 525864
137 + 525727 = 525864
151 + 525713 = 525864
167 + 525697 = 525864
193 + 525671 = 525864
223 + 525641 = 525864
257 + 525607 = 525864

Showing the first eight; more decompositions exist.
