Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 522418, here are decompositions:

5 + 522413 = 522418
47 + 522371 = 522418
101 + 522317 = 522418
137 + 522281 = 522418
167 + 522251 = 522418
179 + 522239 = 522418
191 + 522227 = 522418
227 + 522191 = 522418

Showing the first eight; more decompositions exist.
