Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 481838, here are decompositions:

31 + 481807 = 481838
37 + 481801 = 481838
139 + 481699 = 481838
157 + 481681 = 481838
199 + 481639 = 481838
307 + 481531 = 481838
337 + 481501 = 481838
349 + 481489 = 481838

Showing the first eight; more decompositions exist.
