Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31532010, here are decompositions:

7 + 31532003 = 31532010
43 + 31531967 = 31532010
79 + 31531931 = 31532010
89 + 31531921 = 31532010
101 + 31531909 = 31532010
127 + 31531883 = 31532010
193 + 31531817 = 31532010
197 + 31531813 = 31532010

Showing the first eight; more decompositions exist.
