Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 978438, here are decompositions:

11 + 978427 = 978438
79 + 978359 = 978438
89 + 978349 = 978438
101 + 978337 = 978438
151 + 978287 = 978438
199 + 978239 = 978438
229 + 978209 = 978438
257 + 978181 = 978438

Showing the first eight; more decompositions exist.
