Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 491312, here are decompositions:

13 + 491299 = 491312
61 + 491251 = 491312
163 + 491149 = 491312
229 + 491083 = 491312
271 + 491041 = 491312
421 + 490891 = 491312
463 + 490849 = 491312
541 + 490771 = 491312

Showing the first eight; more decompositions exist.
