Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 525664, here are decompositions:

23 + 525641 = 525664
71 + 525593 = 525664
131 + 525533 = 525664
173 + 525491 = 525664
197 + 525467 = 525664
233 + 525431 = 525664
311 + 525353 = 525664
443 + 525221 = 525664

Showing the first eight; more decompositions exist.
