Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 87982, here are decompositions:

5 + 87977 = 87982
23 + 87959 = 87982
71 + 87911 = 87982
101 + 87881 = 87982
113 + 87869 = 87982
149 + 87833 = 87982
179 + 87803 = 87982
239 + 87743 = 87982

Showing the first eight; more decompositions exist.
