Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 971438, here are decompositions:

19 + 971419 = 971438
37 + 971401 = 971438
67 + 971371 = 971438
157 + 971281 = 971438
241 + 971197 = 971438
409 + 971029 = 971438
439 + 970999 = 971438
499 + 970939 = 971438

Showing the first eight; more decompositions exist.
