Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 556126, here are decompositions:

3 + 556123 = 556126
23 + 556103 = 556126
59 + 556067 = 556126
83 + 556043 = 556126
89 + 556037 = 556126
173 + 555953 = 556126
269 + 555857 = 556126
359 + 555767 = 556126

Showing the first eight; more decompositions exist.
