Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 556748, here are decompositions:

7 + 556741 = 556748
61 + 556687 = 556748
97 + 556651 = 556748
109 + 556639 = 556748
139 + 556609 = 556748
211 + 556537 = 556748
229 + 556519 = 556748
271 + 556477 = 556748

Showing the first eight; more decompositions exist.
