Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 525738, here are decompositions:

7 + 525731 = 525738
11 + 525727 = 525738
19 + 525719 = 525738
29 + 525709 = 525738
41 + 525697 = 525738
61 + 525677 = 525738
67 + 525671 = 525738
89 + 525649 = 525738

Showing the first eight; more decompositions exist.
