Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 491522, here are decompositions:

19 + 491503 = 491522
61 + 491461 = 491522
151 + 491371 = 491522
181 + 491341 = 491522
193 + 491329 = 491522
223 + 491299 = 491522
271 + 491251 = 491522
373 + 491149 = 491522

Showing the first eight; more decompositions exist.
