Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 491452, here are decompositions:

23 + 491429 = 491452
29 + 491423 = 491452
113 + 491339 = 491452
173 + 491279 = 491452
179 + 491273 = 491452
191 + 491261 = 491452
233 + 491219 = 491452
239 + 491213 = 491452

Showing the first eight; more decompositions exist.
