Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 123522, here are decompositions:

5 + 123517 = 123522
19 + 123503 = 123522
23 + 123499 = 123522
29 + 123493 = 123522
31 + 123491 = 123522
43 + 123479 = 123522
73 + 123449 = 123522
83 + 123439 = 123522

Showing the first eight; more decompositions exist.
