Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 978608, here are decompositions:

67 + 978541 = 978608
97 + 978511 = 978608
151 + 978457 = 978608
181 + 978427 = 978608
271 + 978337 = 978608
331 + 978277 = 978608
457 + 978151 = 978608
541 + 978067 = 978608

Showing the first eight; more decompositions exist.
