Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 481906, here are decompositions:

23 + 481883 = 481906
59 + 481847 = 481906
137 + 481769 = 481906
233 + 481673 = 481906
239 + 481667 = 481906
317 + 481589 = 481906
563 + 481343 = 481906
599 + 481307 = 481906

Showing the first eight; more decompositions exist.
