Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 522686, here are decompositions:

7 + 522679 = 522686
13 + 522673 = 522686
163 + 522523 = 522686
277 + 522409 = 522686
313 + 522373 = 522686
349 + 522337 = 522686
397 + 522289 = 522686
457 + 522229 = 522686

Showing the first eight; more decompositions exist.
