Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 491612, here are decompositions:

19 + 491593 = 491612
31 + 491581 = 491612
73 + 491539 = 491612
109 + 491503 = 491612
151 + 491461 = 491612
241 + 491371 = 491612
271 + 491341 = 491612
283 + 491329 = 491612

Showing the first eight; more decompositions exist.
