Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 974978, here are decompositions:

7 + 974971 = 974978
19 + 974959 = 974978
157 + 974821 = 974978
229 + 974749 = 974978
241 + 974737 = 974978
271 + 974707 = 974978
379 + 974599 = 974978
397 + 974581 = 974978

Showing the first eight; more decompositions exist.
