Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 556672, here are decompositions:

59 + 556613 = 556672
71 + 556601 = 556672
89 + 556583 = 556672
113 + 556559 = 556672
269 + 556403 = 556672
359 + 556313 = 556672
383 + 556289 = 556672
401 + 556271 = 556672

Showing the first eight; more decompositions exist.
