Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 87936, here are decompositions:

5 + 87931 = 87936
19 + 87917 = 87936
59 + 87877 = 87936
67 + 87869 = 87936
83 + 87853 = 87936
103 + 87833 = 87936
139 + 87797 = 87936
193 + 87743 = 87936

Showing the first eight; more decompositions exist.
