Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 491422, here are decompositions:

5 + 491417 = 491422
83 + 491339 = 491422
89 + 491333 = 491422
149 + 491273 = 491422
251 + 491171 = 491422
263 + 491159 = 491422
293 + 491129 = 491422
383 + 491039 = 491422

Showing the first eight; more decompositions exist.
