Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 491914, here are decompositions:

41 + 491873 = 491914
47 + 491867 = 491914
131 + 491783 = 491914
167 + 491747 = 491914
263 + 491651 = 491914
281 + 491633 = 491914
383 + 491531 = 491914
431 + 491483 = 491914

Showing the first eight; more decompositions exist.
