Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 978428, here are decompositions:

79 + 978349 = 978428
151 + 978277 = 978428
211 + 978217 = 978428
271 + 978157 = 978428
277 + 978151 = 978428
337 + 978091 = 978428
349 + 978079 = 978428
379 + 978049 = 978428

Showing the first eight; more decompositions exist.
