Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 87948, here are decompositions:

5 + 87943 = 87948
17 + 87931 = 87948
31 + 87917 = 87948
37 + 87911 = 87948
61 + 87887 = 87948
67 + 87881 = 87948
71 + 87877 = 87948
79 + 87869 = 87948

Showing the first eight; more decompositions exist.
