Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 556394, here are decompositions:

43 + 556351 = 556394
67 + 556327 = 556394
73 + 556321 = 556394
127 + 556267 = 556394
151 + 556243 = 556394
271 + 556123 = 556394
367 + 556027 = 556394
373 + 556021 = 556394

Showing the first eight; more decompositions exist.
