Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 556242, here are decompositions:

13 + 556229 = 556242
23 + 556219 = 556242
31 + 556211 = 556242
61 + 556181 = 556242
83 + 556159 = 556242
139 + 556103 = 556242
149 + 556093 = 556242
173 + 556069 = 556242

Showing the first eight; more decompositions exist.
