Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 978392, here are decompositions:

3 + 978389 = 978392
43 + 978349 = 978392
109 + 978283 = 978392
211 + 978181 = 978392
241 + 978151 = 978392
313 + 978079 = 978392
421 + 977971 = 978392
601 + 977791 = 978392

Showing the first eight; more decompositions exist.
