Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 131828, here are decompositions:

31 + 131797 = 131828
79 + 131749 = 131828
97 + 131731 = 131828
127 + 131701 = 131828
157 + 131671 = 131828
211 + 131617 = 131828
331 + 131497 = 131828
349 + 131479 = 131828

Showing the first eight; more decompositions exist.
