Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 101120, here are decompositions:

3 + 101117 = 101120
7 + 101113 = 101120
13 + 101107 = 101120
31 + 101089 = 101120
139 + 100981 = 101120
163 + 100957 = 101120
193 + 100927 = 101120
373 + 100747 = 101120

Showing the first eight; more decompositions exist.
