Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 556874, here are decompositions:

7 + 556867 = 556874
13 + 556861 = 556874
151 + 556723 = 556874
181 + 556693 = 556874
223 + 556651 = 556874
337 + 556537 = 556874
397 + 556477 = 556874
433 + 556441 = 556874

Showing the first eight; more decompositions exist.
