Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 131394, here are decompositions:

13 + 131381 = 131394
23 + 131371 = 131394
31 + 131363 = 131394
37 + 131357 = 131394
73 + 131321 = 131394
83 + 131311 = 131394
97 + 131297 = 131394
101 + 131293 = 131394

Showing the first eight; more decompositions exist.
