Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 978430, here are decompositions:

3 + 978427 = 978430
17 + 978413 = 978430
41 + 978389 = 978430
71 + 978359 = 978430
83 + 978347 = 978430
107 + 978323 = 978430
191 + 978239 = 978430
197 + 978233 = 978430

Showing the first eight; more decompositions exist.
