Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8737408, here are decompositions:

59 + 8737349 = 8737408
107 + 8737301 = 8737408
131 + 8737277 = 8737408
137 + 8737271 = 8737408
269 + 8737139 = 8737408
311 + 8737097 = 8737408
347 + 8737061 = 8737408
359 + 8737049 = 8737408

Showing the first eight; more decompositions exist.
