Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 525804, here are decompositions:

23 + 525781 = 525804
31 + 525773 = 525804
73 + 525731 = 525804
107 + 525697 = 525804
127 + 525677 = 525804
163 + 525641 = 525804
197 + 525607 = 525804
211 + 525593 = 525804

Showing the first eight; more decompositions exist.
