Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 111920, here are decompositions:

7 + 111913 = 111920
73 + 111847 = 111920
139 + 111781 = 111920
199 + 111721 = 111920
223 + 111697 = 111920
283 + 111637 = 111920
433 + 111487 = 111920
547 + 111373 = 111920

Showing the first eight; more decompositions exist.
