Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 71560, here are decompositions:

11 + 71549 = 71560
23 + 71537 = 71560
89 + 71471 = 71560
107 + 71453 = 71560
131 + 71429 = 71560
149 + 71411 = 71560
173 + 71387 = 71560
197 + 71363 = 71560

Showing the first eight; more decompositions exist.
