Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 561788, here are decompositions:

181 + 561607 = 561788
229 + 561559 = 561788
349 + 561439 = 561788
379 + 561409 = 561788
421 + 561367 = 561788
607 + 561181 = 561788
691 + 561097 = 561788
709 + 561079 = 561788

Showing the first eight; more decompositions exist.
