Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8810, here are decompositions:

3 + 8807 = 8810
7 + 8803 = 8810
31 + 8779 = 8810
73 + 8737 = 8810
79 + 8731 = 8810
97 + 8713 = 8810
103 + 8707 = 8810
163 + 8647 = 8810

Showing the first eight; more decompositions exist.
