Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 563978, here are decompositions:

7 + 563971 = 563978
31 + 563947 = 563978
97 + 563881 = 563978
109 + 563869 = 563978
127 + 563851 = 563978
157 + 563821 = 563978
379 + 563599 = 563978
577 + 563401 = 563978

Showing the first eight; more decompositions exist.
