Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 11312, here are decompositions:

13 + 11299 = 11312
61 + 11251 = 11312
73 + 11239 = 11312
139 + 11173 = 11312
151 + 11161 = 11312
163 + 11149 = 11312
181 + 11131 = 11312
193 + 11119 = 11312

Showing the first eight; more decompositions exist.
