Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 561432, here are decompositions:

13 + 561419 = 561432
23 + 561409 = 561432
43 + 561389 = 561432
59 + 561373 = 561432
73 + 561359 = 561432
89 + 561343 = 561432
181 + 561251 = 561432
233 + 561199 = 561432

Showing the first eight; more decompositions exist.
