Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 561782, here are decompositions:

79 + 561703 = 561782
223 + 561559 = 561782
229 + 561553 = 561782
373 + 561409 = 561782
409 + 561373 = 561782
439 + 561343 = 561782
601 + 561181 = 561782
673 + 561109 = 561782

Showing the first eight; more decompositions exist.
