Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 87682, here are decompositions:

3 + 87679 = 87682
11 + 87671 = 87682
41 + 87641 = 87682
53 + 87629 = 87682
59 + 87623 = 87682
173 + 87509 = 87682
191 + 87491 = 87682
239 + 87443 = 87682

Showing the first eight; more decompositions exist.
