Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 87616, here are decompositions:

3 + 87613 = 87616
29 + 87587 = 87616
59 + 87557 = 87616
107 + 87509 = 87616
173 + 87443 = 87616
233 + 87383 = 87616
257 + 87359 = 87616
293 + 87323 = 87616

Showing the first eight; more decompositions exist.
