Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 491702, here are decompositions:

109 + 491593 = 491702
163 + 491539 = 491702
199 + 491503 = 491702
241 + 491461 = 491702
331 + 491371 = 491702
349 + 491353 = 491702
373 + 491329 = 491702
619 + 491083 = 491702

Showing the first eight; more decompositions exist.
