Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 978390, here are decompositions:

31 + 978359 = 978390
41 + 978349 = 978390
43 + 978347 = 978390
47 + 978343 = 978390
53 + 978337 = 978390
67 + 978323 = 978390
103 + 978287 = 978390
107 + 978283 = 978390

Showing the first eight; more decompositions exist.
