Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 561998, here are decompositions:

37 + 561961 = 561998
67 + 561931 = 561998
211 + 561787 = 561998
331 + 561667 = 561998
439 + 561559 = 561998
631 + 561367 = 561998
691 + 561307 = 561998
769 + 561229 = 561998

Showing the first eight; more decompositions exist.
