Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 87634, here are decompositions:

3 + 87631 = 87634
5 + 87629 = 87634
11 + 87623 = 87634
47 + 87587 = 87634
191 + 87443 = 87634
227 + 87407 = 87634
251 + 87383 = 87634
311 + 87323 = 87634

Showing the first eight; more decompositions exist.
