Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31576060, here are decompositions:

11 + 31576049 = 31576060
23 + 31576037 = 31576060
29 + 31576031 = 31576060
53 + 31576007 = 31576060
59 + 31576001 = 31576060
137 + 31575923 = 31576060
167 + 31575893 = 31576060
179 + 31575881 = 31576060

Showing the first eight; more decompositions exist.
