Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 978448, here are decompositions:

59 + 978389 = 978448
89 + 978359 = 978448
101 + 978347 = 978448
179 + 978269 = 978448
239 + 978209 = 978448
269 + 978179 = 978448
431 + 978017 = 978448
521 + 977927 = 978448

Showing the first eight; more decompositions exist.
