Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 556726, here are decompositions:

3 + 556723 = 556726
17 + 556709 = 556726
29 + 556697 = 556726
47 + 556679 = 556726
113 + 556613 = 556726
167 + 556559 = 556726
239 + 556487 = 556726
353 + 556373 = 556726

Showing the first eight; more decompositions exist.
