Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31472010, here are decompositions:

7 + 31472003 = 31472010
19 + 31471991 = 31472010
43 + 31471967 = 31472010
71 + 31471939 = 31472010
103 + 31471907 = 31472010
109 + 31471901 = 31472010
127 + 31471883 = 31472010
179 + 31471831 = 31472010

Showing the first eight; more decompositions exist.
