Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 561480, here are decompositions:

19 + 561461 = 561480
41 + 561439 = 561480
61 + 561419 = 561480
71 + 561409 = 561480
103 + 561377 = 561480
107 + 561373 = 561480
113 + 561367 = 561480
137 + 561343 = 561480

Showing the first eight; more decompositions exist.
