Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 87964, here are decompositions:

3 + 87961 = 87964
5 + 87959 = 87964
47 + 87917 = 87964
53 + 87911 = 87964
83 + 87881 = 87964
131 + 87833 = 87964
167 + 87797 = 87964
197 + 87767 = 87964

Showing the first eight; more decompositions exist.
