Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 131466, here are decompositions:

17 + 131449 = 131466
19 + 131447 = 131466
29 + 131437 = 131466
53 + 131413 = 131466
103 + 131363 = 131466
109 + 131357 = 131466
149 + 131317 = 131466
163 + 131303 = 131466

Showing the first eight; more decompositions exist.
