Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 88866, here are decompositions:

5 + 88861 = 88866
13 + 88853 = 88866
23 + 88843 = 88866
47 + 88819 = 88866
53 + 88813 = 88866
59 + 88807 = 88866
67 + 88799 = 88866
73 + 88793 = 88866

Showing the first eight; more decompositions exist.
