Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 469988, here are decompositions:

19 + 469969 = 469988
31 + 469957 = 469988
97 + 469891 = 469988
109 + 469879 = 469988
139 + 469849 = 469988
241 + 469747 = 469988
271 + 469717 = 469988
331 + 469657 = 469988

Showing the first eight; more decompositions exist.
