Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 971442, here are decompositions:

13 + 971429 = 971442
23 + 971419 = 971442
41 + 971401 = 971442
53 + 971389 = 971442
61 + 971381 = 971442
71 + 971371 = 971442
89 + 971353 = 971442
103 + 971339 = 971442

Showing the first eight; more decompositions exist.
