Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 561486, here are decompositions:

47 + 561439 = 561486
67 + 561419 = 561486
97 + 561389 = 561486
109 + 561377 = 561486
113 + 561373 = 561486
127 + 561359 = 561486
139 + 561347 = 561486
173 + 561313 = 561486

Showing the first eight; more decompositions exist.
