Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 13190, here are decompositions:

3 + 13187 = 13190
7 + 13183 = 13190
13 + 13177 = 13190
19 + 13171 = 13190
31 + 13159 = 13190
43 + 13147 = 13190
97 + 13093 = 13190
127 + 13063 = 13190

Showing the first eight; more decompositions exist.
