Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 978674, here are decompositions:

31 + 978643 = 978674
163 + 978511 = 978674
211 + 978463 = 978674
271 + 978403 = 978674
331 + 978343 = 978674
337 + 978337 = 978674
397 + 978277 = 978674
457 + 978217 = 978674

Showing the first eight; more decompositions exist.
