Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 491252, here are decompositions:

103 + 491149 = 491252
193 + 491059 = 491252
211 + 491041 = 491252
283 + 490969 = 491252
331 + 490921 = 491252
661 + 490591 = 491252
673 + 490579 = 491252
709 + 490543 = 491252

Showing the first eight; more decompositions exist.
