Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 131066, here are decompositions:

3 + 131063 = 131066
7 + 131059 = 131066
43 + 131023 = 131066
79 + 130987 = 131066
97 + 130969 = 131066
109 + 130957 = 131066
139 + 130927 = 131066
193 + 130873 = 131066

Showing the first eight; more decompositions exist.
