Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 521466, here are decompositions:

19 + 521447 = 521466
37 + 521429 = 521466
67 + 521399 = 521466
73 + 521393 = 521466
89 + 521377 = 521466
97 + 521369 = 521466
103 + 521363 = 521466
107 + 521359 = 521466

Showing the first eight; more decompositions exist.
