Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 131004, here are decompositions:

17 + 130987 = 131004
23 + 130981 = 131004
31 + 130973 = 131004
47 + 130957 = 131004
131 + 130873 = 131004
163 + 130841 = 131004
193 + 130811 = 131004
197 + 130807 = 131004

Showing the first eight; more decompositions exist.
