Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 126918, here are decompositions:

5 + 126913 = 126918
59 + 126859 = 126918
61 + 126857 = 126918
67 + 126851 = 126918
79 + 126839 = 126918
137 + 126781 = 126918
157 + 126761 = 126918
167 + 126751 = 126918

Showing the first eight; more decompositions exist.
