Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 111880, here are decompositions:

11 + 111869 = 111880
17 + 111863 = 111880
23 + 111857 = 111880
47 + 111833 = 111880
53 + 111827 = 111880
59 + 111821 = 111880
89 + 111791 = 111880
101 + 111779 = 111880

Showing the first eight; more decompositions exist.
