Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 481930, here are decompositions:

47 + 481883 = 481930
83 + 481847 = 481930
179 + 481751 = 481930
233 + 481697 = 481930
257 + 481673 = 481930
263 + 481667 = 481930
311 + 481619 = 481930
353 + 481577 = 481930

Showing the first eight; more decompositions exist.
