Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 87910, here are decompositions:

23 + 87887 = 87910
29 + 87881 = 87910
41 + 87869 = 87910
107 + 87803 = 87910
113 + 87797 = 87910
167 + 87743 = 87910
191 + 87719 = 87910
227 + 87683 = 87910

Showing the first eight; more decompositions exist.
