Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 87892, here are decompositions:

5 + 87887 = 87892
11 + 87881 = 87892
23 + 87869 = 87892
59 + 87833 = 87892
89 + 87803 = 87892
149 + 87743 = 87892
173 + 87719 = 87892
191 + 87701 = 87892

Showing the first eight; more decompositions exist.
