Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 561558, here are decompositions:

5 + 561553 = 561558
7 + 561551 = 561558
29 + 561529 = 561558
37 + 561521 = 561558
97 + 561461 = 561558
139 + 561419 = 561558
149 + 561409 = 561558
181 + 561377 = 561558

Showing the first eight; more decompositions exist.
