Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 122562, here are decompositions:

5 + 122557 = 122562
29 + 122533 = 122562
53 + 122509 = 122562
59 + 122503 = 122562
61 + 122501 = 122562
73 + 122489 = 122562
109 + 122453 = 122562
113 + 122449 = 122562

Showing the first eight; more decompositions exist.
