Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 87984, here are decompositions:

7 + 87977 = 87984
11 + 87973 = 87984
23 + 87961 = 87984
41 + 87943 = 87984
53 + 87931 = 87984
67 + 87917 = 87984
73 + 87911 = 87984
97 + 87887 = 87984

Showing the first eight; more decompositions exist.
