Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 87882, here are decompositions:

5 + 87877 = 87882
13 + 87869 = 87882
29 + 87853 = 87882
71 + 87811 = 87882
79 + 87803 = 87882
89 + 87793 = 87882
131 + 87751 = 87882
139 + 87743 = 87882

Showing the first eight; more decompositions exist.
