Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31534120, here are decompositions:

3 + 31534117 = 31534120
17 + 31534103 = 31534120
41 + 31534079 = 31534120
47 + 31534073 = 31534120
53 + 31534067 = 31534120
197 + 31533923 = 31534120
281 + 31533839 = 31534120
347 + 31533773 = 31534120

Showing the first eight; more decompositions exist.
