Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 561382, here are decompositions:

5 + 561377 = 561382
23 + 561359 = 561382
131 + 561251 = 561382
191 + 561191 = 561382
281 + 561101 = 561382
443 + 560939 = 561382
491 + 560891 = 561382
509 + 560873 = 561382

Showing the first eight; more decompositions exist.
