Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 556066, here are decompositions:

23 + 556043 = 556066
29 + 556037 = 556066
59 + 556007 = 556066
113 + 555953 = 556066
239 + 555827 = 556066
359 + 555707 = 556066
383 + 555683 = 556066
389 + 555677 = 556066

Showing the first eight; more decompositions exist.
