Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 18412, here are decompositions:

11 + 18401 = 18412
41 + 18371 = 18412
59 + 18353 = 18412
71 + 18341 = 18412
83 + 18329 = 18412
101 + 18311 = 18412
179 + 18233 = 18412
263 + 18149 = 18412

Showing the first eight; more decompositions exist.
