Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1001426, here are decompositions:

37 + 1001389 = 1001426
73 + 1001353 = 1001426
79 + 1001347 = 1001426
103 + 1001323 = 1001426
229 + 1001197 = 1001426
337 + 1001089 = 1001426
409 + 1001017 = 1001426
457 + 1000969 = 1001426

Showing the first eight; more decompositions exist.
