Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1045388, here are decompositions:

67 + 1045321 = 1045388
79 + 1045309 = 1045388
151 + 1045237 = 1045388
271 + 1045117 = 1045388
277 + 1045111 = 1045388
307 + 1045081 = 1045388
367 + 1045021 = 1045388
457 + 1044931 = 1045388

Showing the first eight; more decompositions exist.
