Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 557226, here are decompositions:

29 + 557197 = 557226
67 + 557159 = 557226
73 + 557153 = 557226
139 + 557087 = 557226
157 + 557069 = 557226
167 + 557059 = 557226
193 + 557033 = 557226
199 + 557027 = 557226

Showing the first eight; more decompositions exist.
