Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 561694, here are decompositions:

173 + 561521 = 561694
233 + 561461 = 561694
317 + 561377 = 561694
347 + 561347 = 561694
443 + 561251 = 561694
503 + 561191 = 561694
521 + 561173 = 561694
593 + 561101 = 561694

Showing the first eight; more decompositions exist.
