Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 87810, here are decompositions:

7 + 87803 = 87810
13 + 87797 = 87810
17 + 87793 = 87810
43 + 87767 = 87810
59 + 87751 = 87810
67 + 87743 = 87810
71 + 87739 = 87810
89 + 87721 = 87810

Showing the first eight; more decompositions exist.
