Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 978746, here are decompositions:

3 + 978743 = 978746
19 + 978727 = 978746
103 + 978643 = 978746
127 + 978619 = 978746
283 + 978463 = 978746
397 + 978349 = 978746
409 + 978337 = 978746
463 + 978283 = 978746

Showing the first eight; more decompositions exist.
