Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 111144, here are decompositions:

17 + 111127 = 111144
23 + 111121 = 111144
41 + 111103 = 111144
53 + 111091 = 111144
101 + 111043 = 111144
113 + 111031 = 111144
167 + 110977 = 111144
193 + 110951 = 111144

Showing the first eight; more decompositions exist.
