Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 481382, here are decompositions:

3 + 481379 = 481382
19 + 481363 = 481382
79 + 481303 = 481382
151 + 481231 = 481382
211 + 481171 = 481382
229 + 481153 = 481382
241 + 481141 = 481382
331 + 481051 = 481382

Showing the first eight; more decompositions exist.
