Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 15606, here are decompositions:

5 + 15601 = 15606
23 + 15583 = 15606
37 + 15569 = 15606
47 + 15559 = 15606
79 + 15527 = 15606
109 + 15497 = 15606
113 + 15493 = 15606
139 + 15467 = 15606

Showing the first eight; more decompositions exist.
