Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 491382, here are decompositions:

5 + 491377 = 491382
11 + 491371 = 491382
29 + 491353 = 491382
41 + 491341 = 491382
43 + 491339 = 491382
53 + 491329 = 491382
83 + 491299 = 491382
103 + 491279 = 491382

Showing the first eight; more decompositions exist.
