Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 522658, here are decompositions:

89 + 522569 = 522658
137 + 522521 = 522658
179 + 522479 = 522658
419 + 522239 = 522658
431 + 522227 = 522658
467 + 522191 = 522658
491 + 522167 = 522658
599 + 522059 = 522658

Showing the first eight; more decompositions exist.
