Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 525784, here are decompositions:

3 + 525781 = 525784
11 + 525773 = 525784
53 + 525731 = 525784
71 + 525713 = 525784
107 + 525677 = 525784
113 + 525671 = 525784
191 + 525593 = 525784
251 + 525533 = 525784

Showing the first eight; more decompositions exist.
