Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 491374, here are decompositions:

3 + 491371 = 491374
17 + 491357 = 491374
41 + 491333 = 491374
47 + 491327 = 491374
101 + 491273 = 491374
113 + 491261 = 491374
173 + 491201 = 491374
293 + 491081 = 491374

Showing the first eight; more decompositions exist.
