Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 491704, here are decompositions:

53 + 491651 = 491704
71 + 491633 = 491704
113 + 491591 = 491704
167 + 491537 = 491704
173 + 491531 = 491704
281 + 491423 = 491704
347 + 491357 = 491704
431 + 491273 = 491704

Showing the first eight; more decompositions exist.
