Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 471988, here are decompositions:

29 + 471959 = 471988
59 + 471929 = 471988
197 + 471791 = 471988
239 + 471749 = 471988
269 + 471719 = 471988
311 + 471677 = 471988
317 + 471671 = 471988
347 + 471641 = 471988

Showing the first eight; more decompositions exist.
