Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31576044, here are decompositions:

7 + 31576037 = 31576044
13 + 31576031 = 31576044
37 + 31576007 = 31576044
41 + 31576003 = 31576044
43 + 31576001 = 31576044
53 + 31575991 = 31576044
107 + 31575937 = 31576044
127 + 31575917 = 31576044

Showing the first eight; more decompositions exist.
