Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 491328, here are decompositions:

29 + 491299 = 491328
31 + 491297 = 491328
67 + 491261 = 491328
109 + 491219 = 491328
127 + 491201 = 491328
157 + 491171 = 491328
179 + 491149 = 491328
191 + 491137 = 491328

Showing the first eight; more decompositions exist.
