Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 978848, here are decompositions:

151 + 978697 = 978848
229 + 978619 = 978848
307 + 978541 = 978848
337 + 978511 = 978848
421 + 978427 = 978848
499 + 978349 = 978848
571 + 978277 = 978848
631 + 978217 = 978848

Showing the first eight; more decompositions exist.
