Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 555218, here are decompositions:

109 + 555109 = 555218
127 + 555091 = 555218
241 + 554977 = 555218
331 + 554887 = 555218
379 + 554839 = 555218
397 + 554821 = 555218
421 + 554797 = 555218
439 + 554779 = 555218

Showing the first eight; more decompositions exist.
