Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 491244, here are decompositions:

31 + 491213 = 491244
43 + 491201 = 491244
73 + 491171 = 491244
107 + 491137 = 491244
163 + 491081 = 491244
241 + 491003 = 491244
251 + 490993 = 491244
277 + 490967 = 491244

Showing the first eight; more decompositions exist.
