Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 491456, here are decompositions:

79 + 491377 = 491456
103 + 491353 = 491456
127 + 491329 = 491456
157 + 491299 = 491456
307 + 491149 = 491456
373 + 491083 = 491456
397 + 491059 = 491456
463 + 490993 = 491456

Showing the first eight; more decompositions exist.
