Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 111912, here are decompositions:

19 + 111893 = 111912
41 + 111871 = 111912
43 + 111869 = 111912
79 + 111833 = 111912
83 + 111829 = 111912
113 + 111799 = 111912
131 + 111781 = 111912
139 + 111773 = 111912

Showing the first eight; more decompositions exist.
