Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31463870, here are decompositions:

13 + 31463857 = 31463870
43 + 31463827 = 31463870
73 + 31463797 = 31463870
103 + 31463767 = 31463870
127 + 31463743 = 31463870
157 + 31463713 = 31463870
181 + 31463689 = 31463870
283 + 31463587 = 31463870

Showing the first eight; more decompositions exist.
