Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 18746, here are decompositions:

3 + 18743 = 18746
67 + 18679 = 18746
109 + 18637 = 18746
163 + 18583 = 18746
193 + 18553 = 18746
223 + 18523 = 18746
229 + 18517 = 18746
307 + 18439 = 18746

Showing the first eight; more decompositions exist.
