Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 18190, here are decompositions:

41 + 18149 = 18190
47 + 18143 = 18190
59 + 18131 = 18190
71 + 18119 = 18190
101 + 18089 = 18190
113 + 18077 = 18190
131 + 18059 = 18190
149 + 18041 = 18190

Showing the first eight; more decompositions exist.
