Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 9190, here are decompositions:

3 + 9187 = 9190
17 + 9173 = 9190
29 + 9161 = 9190
53 + 9137 = 9190
131 + 9059 = 9190
149 + 9041 = 9190
179 + 9011 = 9190
191 + 8999 = 9190

Showing the first eight; more decompositions exist.
