Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 555250, here are decompositions:

29 + 555221 = 555250
41 + 555209 = 555250
83 + 555167 = 555250
107 + 555143 = 555250
131 + 555119 = 555250
167 + 555083 = 555250
173 + 555077 = 555250
197 + 555053 = 555250

Showing the first eight; more decompositions exist.
