Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 111390, here are decompositions:

17 + 111373 = 111390
43 + 111347 = 111390
53 + 111337 = 111390
67 + 111323 = 111390
73 + 111317 = 111390
89 + 111301 = 111390
127 + 111263 = 111390
137 + 111253 = 111390

Showing the first eight; more decompositions exist.
