Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 481538, here are decompositions:

7 + 481531 = 481538
37 + 481501 = 481538
151 + 481387 = 481538
241 + 481297 = 481538
307 + 481231 = 481538
331 + 481207 = 481538
367 + 481171 = 481538
397 + 481141 = 481538

Showing the first eight; more decompositions exist.
