Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 521484, here are decompositions:

13 + 521471 = 521484
37 + 521447 = 521484
83 + 521401 = 521484
107 + 521377 = 521484
127 + 521357 = 521484
167 + 521317 = 521484
233 + 521251 = 521484
241 + 521243 = 521484

Showing the first eight; more decompositions exist.
