Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 89220, here are decompositions:

7 + 89213 = 89220
11 + 89209 = 89220
17 + 89203 = 89220
31 + 89189 = 89220
67 + 89153 = 89220
83 + 89137 = 89220
97 + 89123 = 89220
101 + 89119 = 89220

Showing the first eight; more decompositions exist.
