Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8687950, here are decompositions:

59 + 8687891 = 8687950
71 + 8687879 = 8687950
179 + 8687771 = 8687950
191 + 8687759 = 8687950
251 + 8687699 = 8687950
263 + 8687687 = 8687950
281 + 8687669 = 8687950
347 + 8687603 = 8687950

Showing the first eight; more decompositions exist.
