Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 126788, here are decompositions:

7 + 126781 = 126788
31 + 126757 = 126788
37 + 126751 = 126788
97 + 126691 = 126788
157 + 126631 = 126788
241 + 126547 = 126788
271 + 126517 = 126788
307 + 126481 = 126788

Showing the first eight; more decompositions exist.
