Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 978716, here are decompositions:

3 + 978713 = 978716
19 + 978697 = 978716
73 + 978643 = 978716
97 + 978619 = 978716
313 + 978403 = 978716
367 + 978349 = 978716
373 + 978343 = 978716
379 + 978337 = 978716

Showing the first eight; more decompositions exist.
