Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 18744, here are decompositions:

13 + 18731 = 18744
31 + 18713 = 18744
43 + 18701 = 18744
53 + 18691 = 18744
73 + 18671 = 18744
83 + 18661 = 18744
107 + 18637 = 18744
127 + 18617 = 18744

Showing the first eight; more decompositions exist.
