Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 521486, here are decompositions:

3 + 521483 = 521486
109 + 521377 = 521486
127 + 521359 = 521486
157 + 521329 = 521486
307 + 521179 = 521486
313 + 521173 = 521486
349 + 521137 = 521486
367 + 521119 = 521486

Showing the first eight; more decompositions exist.
