Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 555178, here are decompositions:

11 + 555167 = 555178
59 + 555119 = 555178
101 + 555077 = 555178
137 + 555041 = 555178
149 + 555029 = 555178
227 + 554951 = 555178
251 + 554927 = 555178
389 + 554789 = 555178

Showing the first eight; more decompositions exist.
