Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 555226, here are decompositions:

5 + 555221 = 555226
17 + 555209 = 555226
59 + 555167 = 555226
83 + 555143 = 555226
107 + 555119 = 555226
149 + 555077 = 555226
173 + 555053 = 555226
197 + 555029 = 555226

Showing the first eight; more decompositions exist.
