Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 87562, here are decompositions:

3 + 87559 = 87562
5 + 87557 = 87562
23 + 87539 = 87562
53 + 87509 = 87562
71 + 87491 = 87562
89 + 87473 = 87562
179 + 87383 = 87562
239 + 87323 = 87562

Showing the first eight; more decompositions exist.
