Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1004818, here are decompositions:

71 + 1004747 = 1004818
131 + 1004687 = 1004818
149 + 1004669 = 1004818
167 + 1004651 = 1004818
251 + 1004567 = 1004818
257 + 1004561 = 1004818
281 + 1004537 = 1004818
317 + 1004501 = 1004818

Showing the first eight; more decompositions exist.
