Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1004438, here are decompositions:

37 + 1004401 = 1004438
67 + 1004371 = 1004438
151 + 1004287 = 1004438
229 + 1004209 = 1004438
271 + 1004167 = 1004438
277 + 1004161 = 1004438
349 + 1004089 = 1004438
541 + 1003897 = 1004438

Showing the first eight; more decompositions exist.
