Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 87886, here are decompositions:

5 + 87881 = 87886
17 + 87869 = 87886
53 + 87833 = 87886
83 + 87803 = 87886
89 + 87797 = 87886
167 + 87719 = 87886
257 + 87629 = 87886
263 + 87623 = 87886

Showing the first eight; more decompositions exist.
