Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 111898, here are decompositions:

5 + 111893 = 111898
29 + 111869 = 111898
41 + 111857 = 111898
71 + 111827 = 111898
107 + 111791 = 111898
131 + 111767 = 111898
167 + 111731 = 111898
239 + 111659 = 111898

Showing the first eight; more decompositions exist.
