Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31576038, here are decompositions:

7 + 31576031 = 31576038
29 + 31576009 = 31576038
31 + 31576007 = 31576038
37 + 31576001 = 31576038
47 + 31575991 = 31576038
101 + 31575937 = 31576038
139 + 31575899 = 31576038
157 + 31575881 = 31576038

Showing the first eight; more decompositions exist.
