Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31547010, here are decompositions:

7 + 31547003 = 31547010
13 + 31546997 = 31547010
23 + 31546987 = 31547010
29 + 31546981 = 31547010
41 + 31546969 = 31547010
73 + 31546937 = 31547010
97 + 31546913 = 31547010
101 + 31546909 = 31547010

Showing the first eight; more decompositions exist.
