Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 491848, here are decompositions:

11 + 491837 = 491848
29 + 491819 = 491848
59 + 491789 = 491848
101 + 491747 = 491848
179 + 491669 = 491848
197 + 491651 = 491848
257 + 491591 = 491848
311 + 491537 = 491848

Showing the first eight; more decompositions exist.
