Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 491450, here are decompositions:

73 + 491377 = 491450
79 + 491371 = 491450
97 + 491353 = 491450
109 + 491341 = 491450
151 + 491299 = 491450
199 + 491251 = 491450
283 + 491167 = 491450
313 + 491137 = 491450

Showing the first eight; more decompositions exist.
