Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8890, here are decompositions:

3 + 8887 = 8890
23 + 8867 = 8890
29 + 8861 = 8890
41 + 8849 = 8890
53 + 8837 = 8890
59 + 8831 = 8890
71 + 8819 = 8890
83 + 8807 = 8890

Showing the first eight; more decompositions exist.
