Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31576712, here are decompositions:

3 + 31576709 = 31576712
31 + 31576681 = 31576712
73 + 31576639 = 31576712
163 + 31576549 = 31576712
229 + 31576483 = 31576712
709 + 31576003 = 31576712
883 + 31575829 = 31576712
919 + 31575793 = 31576712

Showing the first eight; more decompositions exist.
