Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 89120, here are decompositions:

7 + 89113 = 89120
13 + 89107 = 89120
19 + 89101 = 89120
37 + 89083 = 89120
79 + 89041 = 89120
103 + 89017 = 89120
127 + 88993 = 89120
151 + 88969 = 89120

Showing the first eight; more decompositions exist.
