Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 15576, here are decompositions:

7 + 15569 = 15576
17 + 15559 = 15576
79 + 15497 = 15576
83 + 15493 = 15576
103 + 15473 = 15576
109 + 15467 = 15576
137 + 15439 = 15576
149 + 15427 = 15576

Showing the first eight; more decompositions exist.
