Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 521468, here are decompositions:

67 + 521401 = 521468
109 + 521359 = 521468
139 + 521329 = 521468
151 + 521317 = 521468
307 + 521161 = 521468
331 + 521137 = 521468
349 + 521119 = 521468
421 + 521047 = 521468

Showing the first eight; more decompositions exist.
