Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 491068, here are decompositions:

29 + 491039 = 491068
101 + 490967 = 491068
131 + 490937 = 491068
191 + 490877 = 491068
239 + 490829 = 491068
449 + 490619 = 491068
491 + 490577 = 491068
509 + 490559 = 491068

Showing the first eight; more decompositions exist.
