Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 555040, here are decompositions:

11 + 555029 = 555040
71 + 554969 = 555040
89 + 554951 = 555040
113 + 554927 = 555040
149 + 554891 = 555040
191 + 554849 = 555040
197 + 554843 = 555040
251 + 554789 = 555040

Showing the first eight; more decompositions exist.
