Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 521308, here are decompositions:

41 + 521267 = 521308
107 + 521201 = 521308
131 + 521177 = 521308
257 + 521051 = 521308
269 + 521039 = 521308
419 + 520889 = 521308
467 + 520841 = 521308
521 + 520787 = 521308

Showing the first eight; more decompositions exist.
