Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 522526, here are decompositions:

3 + 522523 = 522526
5 + 522521 = 522526
29 + 522497 = 522526
47 + 522479 = 522526
113 + 522413 = 522526
293 + 522233 = 522526
359 + 522167 = 522526
443 + 522083 = 522526

Showing the first eight; more decompositions exist.
