Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 556166, here are decompositions:

7 + 556159 = 556166
43 + 556123 = 556166
73 + 556093 = 556166
97 + 556069 = 556166
139 + 556027 = 556166
199 + 555967 = 556166
313 + 555853 = 556166
337 + 555829 = 556166

Showing the first eight; more decompositions exist.
