Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 555208, here are decompositions:

41 + 555167 = 555208
89 + 555119 = 555208
131 + 555077 = 555208
167 + 555041 = 555208
179 + 555029 = 555208
239 + 554969 = 555208
257 + 554951 = 555208
281 + 554927 = 555208

Showing the first eight; more decompositions exist.
