Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8719938, here are decompositions:

107 + 8719831 = 8719938
137 + 8719801 = 8719938
167 + 8719771 = 8719938
191 + 8719747 = 8719938
239 + 8719699 = 8719938
257 + 8719681 = 8719938
277 + 8719661 = 8719938
347 + 8719591 = 8719938

Showing the first eight; more decompositions exist.
