Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 556508, here are decompositions:

31 + 556477 = 556508
67 + 556441 = 556508
109 + 556399 = 556508
157 + 556351 = 556508
181 + 556327 = 556508
229 + 556279 = 556508
241 + 556267 = 556508
331 + 556177 = 556508

Showing the first eight; more decompositions exist.
