Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 522404, here are decompositions:

13 + 522391 = 522404
31 + 522373 = 522404
67 + 522337 = 522404
193 + 522211 = 522404
277 + 522127 = 522404
331 + 522073 = 522404
367 + 522037 = 522404
523 + 521881 = 522404

Showing the first eight; more decompositions exist.
