Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 491582, here are decompositions:

43 + 491539 = 491582
79 + 491503 = 491582
211 + 491371 = 491582
229 + 491353 = 491582
241 + 491341 = 491582
283 + 491299 = 491582
331 + 491251 = 491582
433 + 491149 = 491582

Showing the first eight; more decompositions exist.
