Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 556040, here are decompositions:

3 + 556037 = 556040
13 + 556027 = 556040
19 + 556021 = 556040
73 + 555967 = 556040
109 + 555931 = 556040
211 + 555829 = 556040
349 + 555691 = 556040
379 + 555661 = 556040

Showing the first eight; more decompositions exist.
