Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 978626, here are decompositions:

7 + 978619 = 978626
163 + 978463 = 978626
199 + 978427 = 978626
223 + 978403 = 978626
277 + 978349 = 978626
283 + 978343 = 978626
349 + 978277 = 978626
409 + 978217 = 978626

Showing the first eight; more decompositions exist.
