Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 969440, here are decompositions:

7 + 969433 = 969440
19 + 969421 = 969440
37 + 969403 = 969440
97 + 969343 = 969440
139 + 969301 = 969440
181 + 969259 = 969440
331 + 969109 = 969440
523 + 968917 = 969440

Showing the first eight; more decompositions exist.
