Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 111720, here are decompositions:

23 + 111697 = 111720
53 + 111667 = 111720
61 + 111659 = 111720
67 + 111653 = 111720
79 + 111641 = 111720
83 + 111637 = 111720
97 + 111623 = 111720
109 + 111611 = 111720

Showing the first eight; more decompositions exist.
