Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 978426, here are decompositions:

13 + 978413 = 978426
23 + 978403 = 978426
37 + 978389 = 978426
67 + 978359 = 978426
79 + 978347 = 978426
83 + 978343 = 978426
89 + 978337 = 978426
103 + 978323 = 978426

Showing the first eight; more decompositions exist.
