Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 556618, here are decompositions:

5 + 556613 = 556618
11 + 556607 = 556618
17 + 556601 = 556618
59 + 556559 = 556618
131 + 556487 = 556618
347 + 556271 = 556618
389 + 556229 = 556618
677 + 555941 = 556618

Showing the first eight; more decompositions exist.
