Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8737978, here are decompositions:

107 + 8737871 = 8737978
149 + 8737829 = 8737978
269 + 8737709 = 8737978
281 + 8737697 = 8737978
311 + 8737667 = 8737978
401 + 8737577 = 8737978
449 + 8737529 = 8737978
677 + 8737301 = 8737978

Showing the first eight; more decompositions exist.
