Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 555126, here are decompositions:

7 + 555119 = 555126
17 + 555109 = 555126
29 + 555097 = 555126
43 + 555083 = 555126
53 + 555073 = 555126
73 + 555053 = 555126
83 + 555043 = 555126
97 + 555029 = 555126

Showing the first eight; more decompositions exist.
