Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 525778, here are decompositions:

5 + 525773 = 525778
47 + 525731 = 525778
59 + 525719 = 525778
101 + 525677 = 525778
107 + 525671 = 525778
137 + 525641 = 525778
179 + 525599 = 525778
311 + 525467 = 525778

Showing the first eight; more decompositions exist.
