Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 555140, here are decompositions:

31 + 555109 = 555140
43 + 555097 = 555140
67 + 555073 = 555140
97 + 555043 = 555140
163 + 554977 = 555140
181 + 554959 = 555140
241 + 554899 = 555140
307 + 554833 = 555140

Showing the first eight; more decompositions exist.
