Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31576054, here are decompositions:

5 + 31576049 = 31576054
17 + 31576037 = 31576054
23 + 31576031 = 31576054
47 + 31576007 = 31576054
53 + 31576001 = 31576054
131 + 31575923 = 31576054
137 + 31575917 = 31576054
173 + 31575881 = 31576054

Showing the first eight; more decompositions exist.
