Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 87896, here are decompositions:

19 + 87877 = 87896
43 + 87853 = 87896
103 + 87793 = 87896
157 + 87739 = 87896
199 + 87697 = 87896
283 + 87613 = 87896
307 + 87589 = 87896
313 + 87583 = 87896

Showing the first eight; more decompositions exist.
