Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1047388, here are decompositions:

47 + 1047341 = 1047388
71 + 1047317 = 1047388
107 + 1047281 = 1047388
149 + 1047239 = 1047388
191 + 1047197 = 1047388
257 + 1047131 = 1047388
269 + 1047119 = 1047388
281 + 1047107 = 1047388

Showing the first eight; more decompositions exist.
