Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 15562, here are decompositions:

3 + 15559 = 15562
11 + 15551 = 15562
89 + 15473 = 15562
101 + 15461 = 15562
149 + 15413 = 15562
179 + 15383 = 15562
233 + 15329 = 15562
263 + 15299 = 15562

Showing the first eight; more decompositions exist.
