Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31547934, here are decompositions:

13 + 31547921 = 31547934
17 + 31547917 = 31547934
73 + 31547861 = 31547934
83 + 31547851 = 31547934
97 + 31547837 = 31547934
101 + 31547833 = 31547934
151 + 31547783 = 31547934
227 + 31547707 = 31547934

Showing the first eight; more decompositions exist.
