Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 15526, here are decompositions:

29 + 15497 = 15526
53 + 15473 = 15526
59 + 15467 = 15526
83 + 15443 = 15526
113 + 15413 = 15526
149 + 15377 = 15526
167 + 15359 = 15526
197 + 15329 = 15526

Showing the first eight; more decompositions exist.
