Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 521392, here are decompositions:

23 + 521369 = 521392
29 + 521363 = 521392
83 + 521309 = 521392
149 + 521243 = 521392
191 + 521201 = 521392
239 + 521153 = 521392
353 + 521039 = 521392
383 + 521009 = 521392

Showing the first eight; more decompositions exist.
