Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 978974, here are decompositions:

43 + 978931 = 978974
67 + 978907 = 978974
103 + 978871 = 978974
277 + 978697 = 978974
331 + 978643 = 978974
433 + 978541 = 978974
463 + 978511 = 978974
547 + 978427 = 978974

Showing the first eight; more decompositions exist.
