Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 561436, here are decompositions:

17 + 561419 = 561436
47 + 561389 = 561436
59 + 561377 = 561436
89 + 561347 = 561436
263 + 561173 = 561436
353 + 561083 = 561436
383 + 561053 = 561436
389 + 561047 = 561436

Showing the first eight; more decompositions exist.
