Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 978740, here are decompositions:

13 + 978727 = 978740
43 + 978697 = 978740
97 + 978643 = 978740
199 + 978541 = 978740
229 + 978511 = 978740
277 + 978463 = 978740
283 + 978457 = 978740
313 + 978427 = 978740

Showing the first eight; more decompositions exist.
