Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31576036, here are decompositions:

5 + 31576031 = 31576036
29 + 31576007 = 31576036
113 + 31575923 = 31576036
137 + 31575899 = 31576036
197 + 31575839 = 31576036
269 + 31575767 = 31576036
293 + 31575743 = 31576036
383 + 31575653 = 31576036

Showing the first eight; more decompositions exist.
