Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 561446, here are decompositions:

7 + 561439 = 561446
37 + 561409 = 561446
73 + 561373 = 561446
79 + 561367 = 561446
103 + 561343 = 561446
139 + 561307 = 561446
337 + 561109 = 561446
349 + 561097 = 561446

Showing the first eight; more decompositions exist.
