Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1001438, here are decompositions:

7 + 1001431 = 1001438
37 + 1001401 = 1001438
127 + 1001311 = 1001438
241 + 1001197 = 1001438
331 + 1001107 = 1001438
349 + 1001089 = 1001438
397 + 1001041 = 1001438
421 + 1001017 = 1001438

Showing the first eight; more decompositions exist.
