Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 11140, here are decompositions:

23 + 11117 = 11140
47 + 11093 = 11140
53 + 11087 = 11140
71 + 11069 = 11140
83 + 11057 = 11140
113 + 11027 = 11140
137 + 11003 = 11140
167 + 10973 = 11140

Showing the first eight; more decompositions exist.
