Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 87976, here are decompositions:

3 + 87973 = 87976
17 + 87959 = 87976
59 + 87917 = 87976
89 + 87887 = 87976
107 + 87869 = 87976
173 + 87803 = 87976
179 + 87797 = 87976
233 + 87743 = 87976

Showing the first eight; more decompositions exist.
