Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 491372, here are decompositions:

19 + 491353 = 491372
31 + 491341 = 491372
43 + 491329 = 491372
73 + 491299 = 491372
223 + 491149 = 491372
313 + 491059 = 491372
331 + 491041 = 491372
379 + 490993 = 491372

Showing the first eight; more decompositions exist.
