Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 15634, here are decompositions:

5 + 15629 = 15634
53 + 15581 = 15634
83 + 15551 = 15634
107 + 15527 = 15634
137 + 15497 = 15634
167 + 15467 = 15634
173 + 15461 = 15634
191 + 15443 = 15634

Showing the first eight; more decompositions exist.
