Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 978394, here are decompositions:

5 + 978389 = 978394
47 + 978347 = 978394
71 + 978323 = 978394
107 + 978287 = 978394
191 + 978203 = 978394
281 + 978113 = 978394
317 + 978077 = 978394
353 + 978041 = 978394

Showing the first eight; more decompositions exist.
