Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1023904, here are decompositions:

47 + 1023857 = 1023904
53 + 1023851 = 1023904
71 + 1023833 = 1023904
83 + 1023821 = 1023904
173 + 1023731 = 1023904
251 + 1023653 = 1023904
347 + 1023557 = 1023904
353 + 1023551 = 1023904

Showing the first eight; more decompositions exist.
