Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 15522, here are decompositions:

11 + 15511 = 15522
29 + 15493 = 15522
61 + 15461 = 15522
71 + 15451 = 15522
79 + 15443 = 15522
83 + 15439 = 15522
109 + 15413 = 15522
131 + 15391 = 15522

Showing the first eight; more decompositions exist.
