Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 126950, here are decompositions:

7 + 126943 = 126950
37 + 126913 = 126950
127 + 126823 = 126950
193 + 126757 = 126950
199 + 126751 = 126950
211 + 126739 = 126950
337 + 126613 = 126950
349 + 126601 = 126950

Showing the first eight; more decompositions exist.
