Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 87004, here are decompositions:

11 + 86993 = 87004
23 + 86981 = 87004
53 + 86951 = 87004
167 + 86837 = 87004
191 + 86813 = 87004
233 + 86771 = 87004
251 + 86753 = 87004
293 + 86711 = 87004

Showing the first eight; more decompositions exist.
