Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 978830, here are decompositions:

31 + 978799 = 978830
103 + 978727 = 978830
211 + 978619 = 978830
367 + 978463 = 978830
373 + 978457 = 978830
487 + 978343 = 978830
547 + 978283 = 978830
607 + 978223 = 978830

Showing the first eight; more decompositions exist.
