Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 87636, here are decompositions:

5 + 87631 = 87636
7 + 87629 = 87636
13 + 87623 = 87636
23 + 87613 = 87636
47 + 87589 = 87636
53 + 87583 = 87636
79 + 87557 = 87636
83 + 87553 = 87636

Showing the first eight; more decompositions exist.
