Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 126522, here are decompositions:

5 + 126517 = 126522
23 + 126499 = 126522
29 + 126493 = 126522
31 + 126491 = 126522
41 + 126481 = 126522
61 + 126461 = 126522
79 + 126443 = 126522
89 + 126433 = 126522

Showing the first eight; more decompositions exist.
