Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 561956, here are decompositions:

13 + 561943 = 561956
127 + 561829 = 561956
223 + 561733 = 561956
349 + 561607 = 561956
397 + 561559 = 561956
547 + 561409 = 561956
613 + 561343 = 561956
643 + 561313 = 561956

Showing the first eight; more decompositions exist.
