Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 521296, here are decompositions:

29 + 521267 = 521296
53 + 521243 = 521296
233 + 521063 = 521296
257 + 521039 = 521296
353 + 520943 = 521296
383 + 520913 = 521296
443 + 520853 = 521296
509 + 520787 = 521296

Showing the first eight; more decompositions exist.
