Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 71562, here are decompositions:

11 + 71551 = 71562
13 + 71549 = 71562
59 + 71503 = 71562
79 + 71483 = 71562
83 + 71479 = 71562
89 + 71473 = 71562
109 + 71453 = 71562
149 + 71413 = 71562

Showing the first eight; more decompositions exist.
