Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 491344, here are decompositions:

3 + 491341 = 491344
5 + 491339 = 491344
11 + 491333 = 491344
17 + 491327 = 491344
47 + 491297 = 491344
71 + 491273 = 491344
83 + 491261 = 491344
131 + 491213 = 491344

Showing the first eight; more decompositions exist.
