Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1039378, here are decompositions:

29 + 1039349 = 1039378
71 + 1039307 = 1039378
89 + 1039289 = 1039378
149 + 1039229 = 1039378
191 + 1039187 = 1039378
239 + 1039139 = 1039378
251 + 1039127 = 1039378
269 + 1039109 = 1039378

Showing the first eight; more decompositions exist.
