Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 978404, here are decompositions:

61 + 978343 = 978404
67 + 978337 = 978404
127 + 978277 = 978404
181 + 978223 = 978404
223 + 978181 = 978404
313 + 978091 = 978404
331 + 978073 = 978404
337 + 978067 = 978404

Showing the first eight; more decompositions exist.
