Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 18244, here are decompositions:

11 + 18233 = 18244
53 + 18191 = 18244
101 + 18143 = 18244
113 + 18131 = 18244
167 + 18077 = 18244
197 + 18047 = 18244
257 + 17987 = 18244
263 + 17981 = 18244

Showing the first eight; more decompositions exist.
