Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 491468, here are decompositions:

7 + 491461 = 491468
97 + 491371 = 491468
127 + 491341 = 491468
139 + 491329 = 491468
331 + 491137 = 491468
409 + 491059 = 491468
499 + 490969 = 491468
541 + 490927 = 491468

Showing the first eight; more decompositions exist.
