Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1009408, here are decompositions:

47 + 1009361 = 1009408
89 + 1009319 = 1009408
107 + 1009301 = 1009408
149 + 1009259 = 1009408
251 + 1009157 = 1009408
269 + 1009139 = 1009408
311 + 1009097 = 1009408
347 + 1009061 = 1009408

Showing the first eight; more decompositions exist.
