Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8743908, here are decompositions:

7 + 8743901 = 8743908
29 + 8743879 = 8743908
71 + 8743837 = 8743908
101 + 8743807 = 8743908
137 + 8743771 = 8743908
139 + 8743769 = 8743908
191 + 8743717 = 8743908
197 + 8743711 = 8743908

Showing the first eight; more decompositions exist.
