Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 555772, here are decompositions:

5 + 555767 = 555772
11 + 555761 = 555772
29 + 555743 = 555772
89 + 555683 = 555772
101 + 555671 = 555772
179 + 555593 = 555772
251 + 555521 = 555772
281 + 555491 = 555772

Showing the first eight; more decompositions exist.
