Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 11560, here are decompositions:

11 + 11549 = 11560
41 + 11519 = 11560
71 + 11489 = 11560
89 + 11471 = 11560
113 + 11447 = 11560
137 + 11423 = 11560
149 + 11411 = 11560
167 + 11393 = 11560

Showing the first eight; more decompositions exist.
