Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 111860, here are decompositions:

3 + 111857 = 111860
13 + 111847 = 111860
31 + 111829 = 111860
61 + 111799 = 111860
79 + 111781 = 111860
109 + 111751 = 111860
127 + 111733 = 111860
139 + 111721 = 111860

Showing the first eight; more decompositions exist.
