Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 491206, here are decompositions:

5 + 491201 = 491206
47 + 491159 = 491206
167 + 491039 = 491206
239 + 490967 = 491206
257 + 490949 = 491206
269 + 490937 = 491206
293 + 490913 = 491206
347 + 490859 = 491206

Showing the first eight; more decompositions exist.
