Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 978536, here are decompositions:

73 + 978463 = 978536
79 + 978457 = 978536
109 + 978427 = 978536
193 + 978343 = 978536
199 + 978337 = 978536
313 + 978223 = 978536
379 + 978157 = 978536
457 + 978079 = 978536

Showing the first eight; more decompositions exist.
