Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 491174, here are decompositions:

3 + 491171 = 491174
7 + 491167 = 491174
37 + 491137 = 491174
181 + 490993 = 491174
223 + 490951 = 491174
283 + 490891 = 491174
337 + 490837 = 491174
433 + 490741 = 491174

Showing the first eight; more decompositions exist.
