Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 491432, here are decompositions:

3 + 491429 = 491432
61 + 491371 = 491432
79 + 491353 = 491432
103 + 491329 = 491432
181 + 491251 = 491432
283 + 491149 = 491432
349 + 491083 = 491432
373 + 491059 = 491432

Showing the first eight; more decompositions exist.
