Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 131396, here are decompositions:

79 + 131317 = 131396
103 + 131293 = 131396
193 + 131203 = 131396
283 + 131113 = 131396
337 + 131059 = 131396
373 + 131023 = 131396
409 + 130987 = 131396
439 + 130957 = 131396

Showing the first eight; more decompositions exist.
