Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 561874, here are decompositions:

107 + 561767 = 561874
113 + 561761 = 561874
353 + 561521 = 561874
683 + 561191 = 561874
701 + 561173 = 561874
773 + 561101 = 561874
821 + 561053 = 561874
827 + 561047 = 561874

Showing the first eight; more decompositions exist.
