Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 561532, here are decompositions:

3 + 561529 = 561532
11 + 561521 = 561532
71 + 561461 = 561532
113 + 561419 = 561532
173 + 561359 = 561532
281 + 561251 = 561532
359 + 561173 = 561532
431 + 561101 = 561532

Showing the first eight; more decompositions exist.
