Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 89928, here are decompositions:

5 + 89923 = 89928
11 + 89917 = 89928
19 + 89909 = 89928
29 + 89899 = 89928
31 + 89897 = 89928
37 + 89891 = 89928
61 + 89867 = 89928
79 + 89849 = 89928

Showing the first eight; more decompositions exist.
