Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 561742, here are decompositions:

29 + 561713 = 561742
191 + 561551 = 561742
281 + 561461 = 561742
353 + 561389 = 561742
383 + 561359 = 561742
491 + 561251 = 561742
569 + 561173 = 561742
641 + 561101 = 561742

Showing the first eight; more decompositions exist.
