Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 122526, here are decompositions:

17 + 122509 = 122526
23 + 122503 = 122526
29 + 122497 = 122526
37 + 122489 = 122526
73 + 122453 = 122526
83 + 122443 = 122526
127 + 122399 = 122526
137 + 122389 = 122526

Showing the first eight; more decompositions exist.
