Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 481394, here are decompositions:

7 + 481387 = 481394
31 + 481363 = 481394
97 + 481297 = 481394
163 + 481231 = 481394
223 + 481171 = 481394
241 + 481153 = 481394
271 + 481123 = 481394
307 + 481087 = 481394

Showing the first eight; more decompositions exist.
