Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31576048, here are decompositions:

11 + 31576037 = 31576048
17 + 31576031 = 31576048
41 + 31576007 = 31576048
47 + 31576001 = 31576048
131 + 31575917 = 31576048
149 + 31575899 = 31576048
167 + 31575881 = 31576048
281 + 31575767 = 31576048

Showing the first eight; more decompositions exist.
