Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31534104, here are decompositions:

31 + 31534073 = 31534104
37 + 31534067 = 31534104
47 + 31534057 = 31534104
53 + 31534051 = 31534104
71 + 31534033 = 31534104
137 + 31533967 = 31534104
181 + 31533923 = 31534104
193 + 31533911 = 31534104

Showing the first eight; more decompositions exist.
