Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 561572, here are decompositions:

13 + 561559 = 561572
19 + 561553 = 561572
43 + 561529 = 561572
163 + 561409 = 561572
199 + 561373 = 561572
229 + 561343 = 561572
373 + 561199 = 561572
463 + 561109 = 561572

Showing the first eight; more decompositions exist.
