Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 88818, here are decompositions:

5 + 88813 = 88818
7 + 88811 = 88818
11 + 88807 = 88818
17 + 88801 = 88818
19 + 88799 = 88818
29 + 88789 = 88818
47 + 88771 = 88818
71 + 88747 = 88818

Showing the first eight; more decompositions exist.
