Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1004278, here are decompositions:

5 + 1004273 = 1004278
137 + 1004141 = 1004278
251 + 1004027 = 1004278
347 + 1003931 = 1004278
389 + 1003889 = 1004278
461 + 1003817 = 1004278
491 + 1003787 = 1004278
521 + 1003757 = 1004278

Showing the first eight; more decompositions exist.
