Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 87850, here are decompositions:

17 + 87833 = 87850
47 + 87803 = 87850
53 + 87797 = 87850
83 + 87767 = 87850
107 + 87743 = 87850
131 + 87719 = 87850
149 + 87701 = 87850
167 + 87683 = 87850

Showing the first eight; more decompositions exist.
