Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 491752, here are decompositions:

5 + 491747 = 491752
83 + 491669 = 491752
101 + 491651 = 491752
113 + 491639 = 491752
251 + 491501 = 491752
263 + 491489 = 491752
269 + 491483 = 491752
419 + 491333 = 491752

Showing the first eight; more decompositions exist.
