Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 491224, here are decompositions:

5 + 491219 = 491224
11 + 491213 = 491224
23 + 491201 = 491224
53 + 491171 = 491224
233 + 490991 = 491224
257 + 490967 = 491224
311 + 490913 = 491224
347 + 490877 = 491224

Showing the first eight; more decompositions exist.
