Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 525646, here are decompositions:

5 + 525641 = 525646
47 + 525599 = 525646
53 + 525593 = 525646
113 + 525533 = 525646
179 + 525467 = 525646
269 + 525377 = 525646
293 + 525353 = 525646
347 + 525299 = 525646

Showing the first eight; more decompositions exist.
