Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 561740, here are decompositions:

7 + 561733 = 561740
37 + 561703 = 561740
73 + 561667 = 561740
181 + 561559 = 561740
211 + 561529 = 561740
331 + 561409 = 561740
367 + 561373 = 561740
373 + 561367 = 561740

Showing the first eight; more decompositions exist.
