Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31576010, here are decompositions:

3 + 31576007 = 31576010
7 + 31576003 = 31576010
19 + 31575991 = 31576010
73 + 31575937 = 31576010
181 + 31575829 = 31576010
211 + 31575799 = 31576010
241 + 31575769 = 31576010
283 + 31575727 = 31576010

Showing the first eight; more decompositions exist.
