Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 18312, here are decompositions:

5 + 18307 = 18312
11 + 18301 = 18312
23 + 18289 = 18312
43 + 18269 = 18312
59 + 18253 = 18312
61 + 18251 = 18312
79 + 18233 = 18312
83 + 18229 = 18312

Showing the first eight; more decompositions exist.
