Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 87688, here are decompositions:

5 + 87683 = 87688
17 + 87671 = 87688
47 + 87641 = 87688
59 + 87629 = 87688
101 + 87587 = 87688
131 + 87557 = 87688
149 + 87539 = 87688
179 + 87509 = 87688

Showing the first eight; more decompositions exist.
